glsl_to_tgsi: fix out-of-bounds constant access and crash for uniforms
This fixes piglit shaders@glsl-fs-uniform-array-loop-unroll with immediate
shader compilation - it's a compiler test, so it has never been translated
to TGSI before.

i965: Rewrite ir_tex to ir_txl with lod 0 for vertex shaders
The ir_tex opcode turns into a sample or sample_c message, which will try to
compute derivatives to determine the lod. This produces garbage for
non-fragment shaders where the sample coordinates don't correspond to
subspans.
We fix this by rewriting the opcode from ir_tex to ir_txl and setting the
lod to 0.

i965/skl: Add the header for constant loads outside of the generator
Commit 5a06ee738 added a step to the generator to set up the message
header when generating the VS_OPCODE_PULL_CONSTANT_LOAD_GEN7
instruction. That pseudo opcode is implemented in terms of multiple
actual opcodes, one of which writes to one of the source registers in
order to set up the message header. This causes problems because the
scheduler isn't aware that the source register is written to and it
can end up reorganising the instructions incorrectly such that the
write to the source register overwrites a needed value from a previous
instruction. This problem was presenting itself as a rendering error
in the weapon in Enemy Territory: Quake Wars.
Since commit 588859e1 there is an additional problem that the double
register allocated to include the message header would end up being
split into two. This wasn't happening previously because the code to
split registers was explicitly avoided for instructions that are
sending from the GRF.
This patch fixes both problems by splitting the code to set up the
message header into a new pseudo opcode so that it will be done
outside of the generator. This new opcode has the header register as a
destination so the scheduler can recognise that the register is
written to. This has the additional benefit that the scheduler can
optimise the message header slightly better by moving the mov
instructions further away from the send instructions.
On Skylake it appears to fix the following three Piglit tests without
causing any regressions:
gs-float-array-variable-index
gs-mat3x4-row-major
gs-mat4x3-row-major
I think we actually may need to do something similar for the fs
backend and possibly for message headers from regular texture sampling
but I'm not entirely sure.
v2: Make sure the exec-size is retained as 8 for the mov instruction
to initialise the header from g0. This was accidentally lost
during a rebase on top of 07c571a39f.
Split the patch into two so that the helper function is a separate
change.
Fix emitting the MOV instruction on Gen7.

i965/vec4: Add a helper function to emit VS_OPCODE_PULL_CONSTANT_LOAD
There were three places in the visitor that had a similar chunk of
code to emit the VS_OPCODE_PULL_CONSTANT_LOAD opcode using a register
for the offset. This patch combines the chunks into a helper function
to reduce the code duplication. It will also be useful in the next
patch to expand what happens on Gen9+. This shouldn't introduce any
functional changes.

mesa,glsl: rename `interface` to `programInterface`.
`interface` is a define on Windows -- an alias for `struct` keyword,
used when declaring COM interfaces in C or C++.
So use instead `programInterface`, therefore matching the name used
in GL_ARB_program_interface_query spec/headers, which was renamed exactly
for the same reason:
"Revision 10, May 10, 2012 (pbrown)
- Rename the formal parameter <interface> used by the functions in this
extension to <programInterface>. Certain versions of the Microsoft
C/C++ compiler and/or its headers cause "interface" to be treated as a
reserved keyword."

glx: Create proper server dependency for GLX_EXT_create_context_es2_profile
Previously GLX_EXT_create_context_es2_profile was marked as "direct
only" so that it would not depend on server support. Since the
extension required functions that are part of
GLX_ARB_create_context_profile, support for the EXT was disabled if the
ARB was not supported.
This was complete rubbish. If the server supported the ARB but not the
EXT, sending a request with GLX_CONTEXT_ES2_PROFILE_BIT_EXT would result
in GLXBadProfileARB.
Instead of the misguided hack, make GLX_EXT_create_context_es2_profile
properly depend on server support by not marking it as "direct only."
