i965/skl: Use an exec size of 8 to initialise the message header
Commit
e93566a15c61c33faa changed the message header code needed to
make Skylake use SIMD4x2 so that it uses a register with width 4
instead of 8 as the source register in the send message. However it
also changed the width for the dest in the MOV instruction which is
used to initialise the header register with the values from g0. The
width of the destination is used to determine the exec size in
brw_set_dest so this would end up making the MOV have an exec size of
4. I think this would end up leaving the top half of the register
uninitialised. The top half of the header has meaningful values so
this probably isn't a good idea.
This patch just casts the dest register for the MOV instruction back
to a vec8 to fix it. It doesn't cause any changes to a Piglit run.

i965/fs: Always invert predicate of SEL with swapped arguments
Commit
b616164 added an optimization of b2f generation of a comparison.
It also included an extra optimization of one of the comparison values
is a constant of zero. The trick was that some value was known to be
zero, so that value could be used in the SEL instruction instead of
potentially loading 0.0 into a register.
This change switched the order of the arguments to the SEL, and, for
some unknown reason, I thought that the predicate should therefore
only be inverted for the == case. Clearly, it should always be
inverted.
Fixes piglit fs-notEqual-of-expression.shader_test and

i965: Implement proper workaround for Gen4 GPU CONSTANT_BUFFER hangs.
I finally managed to dig up some information on our mysterious GPU hangs.
A wiki page from the Crestline validation team mentions that they found
a GPU hang in "Serious Sam 2" (on Windows) with remarkably similar
conditions to the ones we've seen in Google Chrome and glmark2.
Apparently, if WM_STATE has "PS Use Source Depth" enabled, CC_STATE has
most depth state disabled, and you issue a CONSTANT_BUFFER command and
immediately draw, the depth interpolator makes a small mistake that
leads to hangs.
Most of the traces I looked at contained a CONSTANT_BUFFER packet
immediately followed by 3DPRIMITIVE, or at least very few packets.
It appears they also have "PS Use Source Depth" enabled - either at the
hang, or a little before it. So I think this is our bug.
The workaround is to emit a non-pipelined state packet after issuing a
CONSTANT_BUFFER packet. This is really similar to the workaround I
developed in commit
c4fd0c9052dd391d6f2e9bb8e6da209dfc7ef35b.

i965: Create NIR during LinkShader() and ProgramStringNotify().
Previously, we translated into NIR and did all the optimizations and
lowering as part of running fs_visitor. This meant that we did all of

SIMD16. We also had to redo it every time we hit a state based
recompile.
We now generate NIR once at link time. ARB programs don't have linking,
so we instead generate it at ProgramStringNotify time.
Mesa's fixed function vertex program handling doesn't bother to inform
the driver about new programs at all (which is rather mean), so we
generate NIR at the last minute, if it hasn't happened already.
shader-db runs ~9.4% faster on my i7-5600U, with a release build.

draw: (trivial) don't print the shader twice with GALLIVM_DEBUG=tgsi (or ir)
Neither the shader nor the key change when doing elts or linear variant, so
this was just annoying (probably mildly useful at some point when we printed
the IR per function too).

gallivm: don't use control flow when doing indirect constant buffer lookups
llvm goes crazy when doing that, using way more memory and time, though there's
probably more to it - this points to a very much similar issue as fixed in
8a9f5ecdb116d0449d63f7b94efbfa8b205d826f. In any case I've seen a quite
plain looking vertex shader with just ~50 simple tgsi instructions (but with a
dozen or so such indirect constant buffer lookups) go from a terribly high
~440ms compile time (consuming 25MB of memory in the process) down to a still
awful ~230ms and 13MB with this fix (with llvm 3.3), so there's still obvious
improvements possible (but I have no clue why it's so slow...).
The resulting shader is most likely also faster (certainly seemed so though
I don't have any hard numbers as it may have been influenced by compile times)
since generally fetching constants outside the buffer range is most likely an
app error (that is we expect all indices to be valid).
It is possible this fixes some mysterious vertex shader slowdowns we've seen
ever since we are conforming to newer apis at least partially (the main draw
loop also has similar looking conditionals which we probably could do without -
if not for the fetch at least for the additional elts condition.)

glsl: check for forced_language_version in is_version()
This is a follow-on fix from the earlier "glsl: allow ForceGLSLVersion
to override #version directives" change. Since we're not changing
the language_version field, we have to check forced_language_version
here.

i965/skl: Fix the order of the arguments for the LD sampler message
In Skylake the order of the arguments for sample messages with the LD
type are u, v, lod, r whereas previously they were u, lod, v, r.
This fixes 144 Piglit tests including ones that directly use
texelFetch and also some using the meta stencil blit path which
appears to use texelFetch in its shader.
