[Mesa-dev] [PATCH 14/22] nir: add legal bit_sizes to intrinsics

With OpenCL some system values match the address bits, but in GLSL we also
have some system values being 64 bit.
With this it is possible to adjust the builder functions so that depending
on the bit_sizes the correct bit_size is used or an additional argument is
added in case of multiple possible values.
Also this allows for further validation
