nir: Add AMD specific intrinsics for merged shaders and NGG.

Browse Source 
These intrinsics represent what the hardware can actually do.
Lowering our shaders to use these intrinsics will allow us to
deal with mapping the classic VS, TES, GS (and the future MS)
stages to the hardware capabilities using NIR, which makes our
backend compilers simpler.
