i965: Fix number of slots in SSO mode when there are no user varyings.
We want vue_map->num_slots to be one more than the final slot.
When assigning fixed slots, built-in slots, and non-SSO user varyings,
we do slot++. This leaves "slot" as one past the most recently assigned
slot. But for SSO user varyings, we computed slot based on the varying
location value...and left it at that slot value.
To work around this inconsistency, I made num_slots be "slot + 1" if
separate and "slot" otherwise. The problem is...if there are no user
varyings in SSO mode...then we would have done slot++ when assigning
built-ins, so it would be off by one. This resulted in loops from 0
to vue_map->num_slots hitting a bonus BRW_VARYING_SLOT_PAD at the end.
This used to break the SIMD8 VS/TES backends, but I fixed that in
commit
480d6c1653713dcae617ac523b2ca5deee01c845. It's probably safe
at this point, but we should fix it anyway.
To fix this, do slot++ in all cases. For SSO mode, we overwrite slot
for every varying, so this increment only matters on the last varying.
Because we process varyings in order, this will set slot to 1 more
than the highest assigned slot.

nir/i965: use two slots from inputs_read for dvec3/dvec4 vertex input attributes
So far, input_reads was a bitmap tracking which vertex input locations
were being used.
In OpenGL, an attribute bigger than a vec4 (like a dvec3 or dvec4)
consumes just one location, any other small attribute. So we mark the
proper bit in inputs_read, and also the same bit in double_inputs_read
if the attribute is a dvec3/dvec4.
But in Vulkan, this is slightly different: a dvec3/dvec4 attribute
consumes two locations, not just one. And hence two bits would be marked
in inputs_read for the same vertex input attribute.
To avoid handling two different situations in NIR, we just choose the
latest one: in OpenGL, when creating NIR from GLSL/IR, any dvec3/dvec4
vertex input attribute is marked with two bits in the inputs_read bitmap
(and also in the double_inputs_read), and following attributes are
adjusted accordingly.
As example, if in our GLSL/IR shader we have three attributes:
layout(location = 0) vec3 attr0;
layout(location = 1) dvec4 attr1;
layout(location = 2) dvec3 attr2;
then in our NIR shader we put attr0 in location 0, attr1 in locations 1
and 2, and attr2 in location 3 and 4.
Checking carefully, basically we are using slots rather than locations
in NIR.
When emitting the vertices, we do a inverse map to know the
corresponding location for each slot.
v2 (Jason):
- use two slots from inputs_read for dvec3/dvec4 NIR from GLSL/IR.
v3 (Jason):
- Fix commit log error.
- Use ladder ifs and fix braces.
- elements_double is divisible by 2, don't need DIV_ROUND_UP().
- Use if ladder instead of a switch.

isl: fix VA64 support for double and dvecN vertex attributes
We use *64*_PASSTHRU formats to upload vertex attributes of 64 bits

"When SourceElementFormat is set to one of the *64*_PASSTHRU
formats, 64-bit components are stored in the URB without any
conversion. In this case, vertex elements must be written as 128
or 256 bits, with VFCOMP_STORE_0 being used to pad the output
as required. E.g., if R64_PASSTHRU is used to copy a 64-bit Red
component into the URB, Component 1 must be specified as
VFCOMP_STORE_0 (with Components 2,3 set to VFCOMP_NOSTORE)
in order to output a 128-bit vertex element, or Components 1-3 must
be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
element. Likewise, use of R64G64B64_PASSTHRU requires Component 3
to be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex

Marking operations as redundant if they are equal to the base

But the opt falls apart with a tree like this:

The problem is that both branches are treated the same: descending in
the left branch will prune the constant, and then descending the right
branch will prune the constant there as well, because limits[0] wasn't
updated to take the change on the left branch into account, and so we
still get [3,\infty) as baserange.

i965: Rework gl_TessLevel*[] handling to use NIR compact arrays.
Treating everything as scalar arrays allows us to drop a bunch of
special case input/output munging all throughout the backend.
Instead, we just need to remap the TessLevel components to the
appropriate patch URB header locations in remap_patch_urb_offsets().
We also switch to treating the TES input versions of these as ordinary
shader inputs rather than system values, as remap_patch_urb_offsets()
just makes everything work out without special handling.
This regresses one Piglit test:
arb_tessellation_shader-large-uniforms/GL_TESS_CONTROL_SHADER-array-at-limit
The compiler starts promoting the constant arrays assigned to gl_TessLevel*
to uniform arrays. Since the shader also has a uniform array that uses
the maximum number of uniform components, this puts it over the uniform
component limit enforced by the linker. This is arguably a bug in the
constant array promotion code (it should avoid pushing us over limits),
but is unlikely to penalize any real application.

llvmpipe: do transpose/untwiddle after conversion for 8bit formats
Generally we should do tranpose after conversion, if the format has less than
32 bits per channel (if it has 32 bits, conversion is going to be a no-op
anyway...). This is obviously because there's less vectors to deal with.
Though the advantage for 16 bit formats isn't that big, and in fact with AVX
there isn't really any (as the 32bit unpacks can be done with 256bit, but
the smaller ones cannot, although that would change again with proper AVX2
support).
Only makes sense for 2d and not 1d cases. And to keep things easy, only handle
1,2 and 4 channels (rgbx is just fine).
For rgba unorm8 format the backend conversion sums up to these instruction
totals (not counting the movs for SSE2 due to 2-op syntax - generally every 2
unpacks need an additional mov).
SSE2 AVX
transpose: 32 unpack 16 unpack
untwiddle: 0 8 (128bit low/high permutes)
convert: 16 mul + 16 cvt 8 mul + 8 cvt
32->8bit: 12 pack 8 (128bit extract) + 12 pack
When doing transpose/untwiddle afterwards we get:
convert: 16 mul + 16 cvt 8 mul + 8 cvt
32->8bit: 12 pack 8 (128bit extract) + 12 pack
transpose/untwiddle 12 unpack 12 unpack
So for SSE2, this drops 20 unpacks (total instruction count 76->56)
whereas for AVX it replaces the 16 256bit unpacks with 8 128bit ones
and drops the 8 lo/hi permutes (in total 60->48). (Albeit to be fair,
the permutes could be dropped even when doing the transpose first,
they are extremely pointless but we'd need to be able to tell
lp_build_conv to reorder the vectors, for AVX2 we're going to need to
be able to tell lp_build_conv about ordering in any case.)
(With different ordering going into conversion, it would be possible
to do 4 unpacks + 4 pshufbs instead of 12 unpacks, but that might not
be better, and not all cpus can do it. Proper AVX2 support should eliminate
the 8 128bit extracts, reduce these 12 packs to 6 and the 12 unpacks to 2
pshufb + 2 permq ideally (+ 2 final 128bit extracts).)

gallivm: generalize 4x4f->1x16ub special case conversion
This special packing path can be easily extended to handle not just
float->unorm8 but also float->snorm8 and uint32->uint8 and int32->int8
(i.e. all interesting cases for llvmpipe fs backend code).
The packing parts all stay the same (only the last step packing will
be signed->signed instead of signed->unsigned but luckily even sse2 can do
both).
While here also note some bugs with that (we keep the bugs identical to
what we did before on x86, albeit other archs may differ). In particular
float->unorm8 too large values will still get clamped to 0, not 255, and for
float->snorm8 NaNs will end up as -1, not 0 (but we do the clamp against 1.0
there to prevent too large values ending up as -1.0 - this is inconsistent
to unorm8 handling but is what we ended up before, I'm not sure we can get
away without it). This is quite fishy in any case as we depend on
arch-dependent behavior of the iround (my understanding is in fact with
altivec the conversion would actually saturate although I've no idea about
NaNs, so probably wouldn't need to do anything for snorm).
(There are only minimal piglit tests for unorm clamping behavior AFAICT, in
particular nothing seems to test values which are too large to be handled by
the float->int conversion.)
For uint32->uint8 we also do a min against MAX_INT, since the source for
the packs is always signed (again, on x86 - should probably be able to
express these arch-dependent bits better some day).

llvmpipe: use scalar load instead of vectors for small vectors in fs backend
llvm has _huge_ problems trying to load things like <4 x i8> vectors and
stitching such loads together to form 128bit vectors. My understanding
of the problem is that the type legalizer tries to extend that to
really a <4 x i32> vector and not a <16 x i8> vector with the 4 elements
first then followed by padding, so the shuffles for then combining things
together are more or less impossible - you can in fact see the pmovzxd
llvm generates. Pre-4.0 llvm just gives up on it completely and does a 30+
pextrb/pinsrb sequence instead.
It looks like current llvm has fixed this behavior (my guess would be
due to better shuffle combination and load/shuffle folds), but we can
avoid this by just loading as <1 x i32> values, combine that and only
cast at the end. (I suspect it might also work if we'd pad the loaded
vectors immediately before shuffling them together, instead of directly
stitching 2 such vectors together pairwise before combining the pair.
But this _might_ lose the ability to load the values directly into
their right place in the vector with pinsrd.). But using 32bit values
is probably easier for llvm as it will never give it funny ideas how
the vector should look like.
(This is possibly only a problem for 1x8bit formats, since 2x8bit will
end up fetching 64bit hence only two vectors are stitched together,
not 4, but we use the same strategy anyway.)

i965: Enable several GLES 3.1 extensions on HSW+
The only reason we didn't previously enable this was the dependency on
OpenGL ES 3.1. These should have been enabled as soon as HSW got
stencil texturing. We also needed to fixup setting MaxViewports.

i965: Always set MaxViewports and related limits
Since
9d6ca7c3, there should be no performance hit for having
MaxViewports > 1. Always set this context state. This eliminates the
need to update this conditional as we add support for OES_viewport_array
on older GPUs.
