spirv_atomic: Define U32x2 storage buffers for 64-bit storage atomics
...
Some drivers do not support 64-bit atomics, and fallback to atomically modifying U32x2 vectors. This change ensures that U32x2 storage vectors are defined in the spir-v shader when 64-bit atomics are used.

shader: Add integer attribute get optimization pass

Works around an nvidia driver bug, where casting the integer attributes to float and back to an integer always returned 0.

shader: Fold integer FMA from Nvidia's pattern
...
Fold shaders doing "a * b + c" on integers from the pattern generated by
Nvidia's GL compiler.
On a somewhat complex compute shader it reduces the code size by 16
instructions from 2 matches on Turing GPUs.
On Intel as extracted from KHR_pipeline_executable_properties:
