ReinUsesLisp a63a0daa5e gl_arb_decompiler: Implement an assembly shader decompiler 
Emit code compatible with NV_gpu_program5.
This should emit code compatible with Fermi, but it wasn't tested on
that architecture. Pascal has some issues not present on Turing GPUs.
ReinUsesLisp 3dcaa84ba4 shader/transform_feedback: Add host API friendly TFB builder
ReinUsesLisp e8efd5a901 video_core: Rename "const buffer locker" to "registry"
ReinUsesLisp bd8b9bbcee gl_shader_cache: Rework shader cache and remove post-specializations 
Instead of pre-specializing shaders and then post-specializing them,
drop the later and only "specialize" the shader while decoding it.

Fernando Sahmkow 1a58f45d76 VideoCore: Unify const buffer accessing along engines and provide ConstBufferLocker class to shaders.
Fernando Sahmkow 47e4f6a52c Shader_Ir: Refactor Decompilation process and allow multiple decompilation modes.

ReinUsesLisp 4e35177e23 shader_ir: Implement VOTE 
Implement VOTE using Nvidia's intrinsics. Documentation about these can
be found here
https://developer.nvidia.com/reading-between-threads-shader-intrinsics

Instead of using portable ARB instructions I opted to use Nvidia
intrinsics because these are the closest we have to how Tegra X1
hardware renders.

To stub VOTE on non-Nvidia drivers (including nouveau) this commit
simulates a GPU with a warp size of one, returning what is meaningful
for the instruction being emulated:

* anyThreadNV(value) -> value
* allThreadsNV(value) -> value
* allThreadsEqualNV(value) -> true

ballotARB, also known as "uint64_t(activeThreadsNV())", emits

VOTE.ANY Rd, PT, PT;

on nouveau's compiler. This doesn't match exactly to Nvidia's code

VOTE.ALL Rd, PT, PT;

Which is emulated with activeThreadsNV() by this commit. In theory this
shouldn't really matter since .ANY, .ALL and .EQ affect the predicates
(set to PT on those cases) and not the registers.
