discard is supposed to be a terminator, killing the thread, so that it's
possible to exit main solely by a discard e.g. inside of an infinite
loop. However, it currently isn't treated as a terminator in NIR due to
workarounds turning it into demote (d3d-style kill) and even if that
were fixed, we probably wouldn't want to treat discard_if as a jump
since otherwise the scheduler wouldn't be able to schedule things around
it. So, add this workaround which inserts jump instructions as
necessary to guarantee that the program always terminates.
This fixes a hang in dEQP-VK.graphicsfuzz.while-inside-switch, which
conditionally does a discard inside an infinite loop.

In SPIRV of compute shader in Aztec Ruins benchmark there is:
OpControlBarrier %uint_1 %uint_1 %uint_0
// ControlBarrier(Device, Device, rdcspv::MemorySemantics(0));
which is an incorrect translation of glsl barrier().
GLSLang, prior to c3f1cdfa, emitted the OpControlBarrier with
Device instead of Workgroup for execution scope.
2365520c covers similar case but isn't applied when execution_scope
is SpvScopeDevice.

For GLVND reasons the client/platform extensions strings should be
split. While in the non GLVND case they're one big string.
Currently we handle this distinction at run-time for not obvious reason.
Adding additional code and complexity.
Swap those with a few well placed #if USE_LIBGLVND guards.
As a side result this removes a minor memory leak due to the
concatenation in the non GLVND case.

I think we're unanimous in wanting to drop nir_lower_to_source_mods.
It's a bit of complexity to handle in the backend, but perhaps more
importantly, would be even more complexity to handle in nir_search.
And, it turns out that since we made other compiler improvements in the
last few years, they no longer appear to buy us anything of value.
Summarizing the results from shader-db from this patch:
- Icelake (scalar mode)
Instruction counts:
- 411 helped, 598 hurt (out of 139,470 shaders)
- 99.2% of shaders remain unaffected. The average increase in
instruction count in hurt programs is 1.78 instructions.
- total instructions in shared programs: 17214951 -> 17215206 (<.01%)
- instructions in affected programs: 1143879 -> 1144134 (0.02%)
Cycles:
- 1042 helped, 1357 hurt
- total cycles in shared programs: 365613294 -> 365882263 (0.07%)
- cycles in affected programs: 138155497 -> 138424466 (0.19%)
- Haswell (both scalar and vector modes)
Instruction counts:
- 73 helped, 1680 hurt (out of 139,470 shaders)
- 98.7% of shaders remain unaffected. The average increase in
instruction count in hurt programs is 1.9 instructions.
- total instructions in shared programs: 14199527 -> 14202262 (0.02%)
- instructions in affected programs: 446499 -> 449234 (0.61%)
Cycles:
- 5253 helped, 5559 hurt
- total cycles in shared programs: 359996545 -> 360038731 (0.01%)
- cycles in affected programs: 155897127 -> 155939313 (0.03%)
Given that ~99% of shader-db remains unaffected, and the affected
programs are hurt by about 1-2 instructions - which are all cheap
ALU instructions - this is unlikely to be measurable in terms of
any real performance impact that would affect users.
So, drop them and simplify the backend, and hopefully enable other
future simplifications in NIR.

In meson 0.54.0 I fixed the llvm cmake dependency to return "not found"
if shared linking is requested. This means that for 0.54.0 and later we
don't need to do anything, and for earlier versions we only need to
change the logic to force the config-tool method if shared linking is
required.
