Second version of the series:
- removed GroupNonUniformArithmetic from supported capabilites as we cannot
guarantee that LLVM WWM liveness issues won't affect the behavior.
- reworked and moved lowering of 64bit shuffle intrinsics to
nir_lower_subgroups.
- Quad shuffles use ds_swizzle on pre-VI hardware or LLVM < 6.
Daniel Schürmann (7):
nir: adjust subgroups instructions for 64bit ballot sizes
nir/spirv: propagate constants of GroupNonUniformQuad instructions,
eliminate warning and fix breaks
nir: lower 64bit subgroup shuffle intrinsics
ac: make ballot and umsb capable of 64bit inputs
ac: add LLVM build functions for subgroup instrinsics
ac: handle subgroup intrinsics
radv: enable subgroup capabilities
