intel/fs: Introduce regioning lowering pass.

This legalization pass is meant to handle situations where the source
or destination regioning controls of an instruction are unsupported by
the hardware and need to be lowered away into separate instructions.
This should be more reliable and future-proof than the current
approach of handling CHV/BXT restrictions manually all over the
visitor.  The same mechanism is leveraged to lower unsupported type
conversions easily, which obsoletes the lower_conversions pass.

v2: Give conditional modifiers the same treatment as predicates for
    SEL instructions in lower_dst_modifiers() (Iago).  Special-case a
    couple of other instructions with inconsistent conditional mod

radeonsi: Fix use of 1- or 2- component GL_DOUBLE vbo's.

With Mesa 18.1, commit be973ed21f6e, si_llvm_load_input_vs()
changed the number of source 32-bit wide dword components
used for fetching vertex attributes into the vertex shader
from a constant 4 to a variable num_channels number, depending
on input data format, with some special case handling for
input data formats like 64-Bit doubles.

In the case of a GL_DOUBLE input data format with one
or two components though, e.g, submitted via ...

a) glTexCoordPointer(1, GL_DOUBLE, 0, buffer);
b) glTexCoordPointer(2, GL_DOUBLE, 0, buffer);

... the input format would be SI_FIX_FETCH_RG_64_FLOAT,
but no special case handling was implemented for that
case, so in the default path the number of 32-bit
dwords would be set to the number of float input components
derived from info->input_usage_mask. This ends with corrupted
input to the vertex shader, because fetching a 64-bit double
from the vbo requires fetching two 32-bit dwords instead of 1,
and fetching a two double input requires 4 dword fetches
instead of 2, so in these cases the vertex shader receives
incomplete/truncated input data:

a) float v = gl_MultiTexCoord0.x;  -> v.x is corrupted.
b) vec2  v = gl_MultiTexCoord0.xy; -> v.x is assigned
   correctly, but v.y is corrupted.

This happens with the standard TGSI IR compiled shaders.
Under NIR with R600_DEBUG=nir, we got correct behavior
because the current radeonsi nir code always assigns
info->input_usage_mask = TGSI_WRITEMASK_XYZW, thereby
always fetches 4 dwords regardless of what the shader
actually needs.

Fix this by properly assigning 2 or 4 dword fetches for
one or two component GL_DOUBLE input.

If there is no last fence, due to no rendering happening yet, just
create a new signaled fence and return it, to match the expectations of
the EGL sync fence API.

Fixes random "Could not create sync fence 0x3003" assertion failures from
Skia on Android, coming from the following code:

https://android.googlesource.com/platform/frameworks/base/+/master/libs/hwui/pipeline/skia/SkiaOpenGLPipeline.cpp#427

Reproducible especially with thread count >= 4.

One could make the driver always keep the reference to the last fence,
but:

 - the driver seems to explicitly destroy the fence whenever a rendering
   pass completes and changing that would require a significant functional
   change to the code. (Specifically, in lp_scene_end_rasterization().)

 - it still wouldn't solve the problem of an EGL sync fence being created
   and waited on without any rendering happening at all, which is
   also likely to happen with Android code pointed to in the commit.

Therefore, the simple approach of always creating a fence is taken,
similarly to other drivers, such as radeonsi.

Tested with piglit llvmpipe suite with no regressions and following
tests fixed:

nir: Make gl_nir_lower_samplers use gl_nir_lower_samplers_as_deref

These days, we have two sampler lowering passes.  The newer one,
gl_nir_lower_samplers_as_deref, is used by radeonsi.  It rewrites
variables to drop structures out of sampler deref chains, to make
life simpler.  It then sets var->data.binding for non-bindless
sampler and image variables based on the GL uniform storage's
opaque index values.

The older one converts sampler deref chains (nir_tex_src_texture_deref)
to a numerical offset (nir_tex_src_texture_offset).  It also stores the
constant-valued portion of that number in tex->texture_index, making
life really simple for drivers that don't support indirects.  It too
pokes at GL uniform storage's opaque index values.

Logically, we can do the first pass (simplify derefs, set bindings)
then the second (turn derefs to offsets, set texture_index).  This
patch does exactly that, eliminating some redundancy (only one pass
has to poke at GL uniform storage), and gaining proper var->data.binding

the array dimensionality again.  For structs, we want to simply use
the new underlying type, skipping the struct altogether.

The correct way to do this is to do nothing at all.  Previously, we

v3d: Stop scalarizing our uniform loads.

We can pull a whole vector in a single indirect load.  This saves a bunch
of round-trips to the TMU, instructions for setting up multiple loads,
references to the UBO base in the uniforms, and apparently manages to
reduce register pressure as well.

In the process of adding support for SSBOs and CS shared vars, I ended up
