[Mesa-dev] [PATCH 1/7] nir: Use uint8_t instead of unsigned for nir_intrinsic_info fields

[Jason Ekstrand]

This cuts the .data section of nir_intrinsics.o by 60%:

   text     data      bss      dec      hex  filename
   1845     8400        0    10245     2805  nir_intrinsics.o
   1845     3360        0     5205     1455  nir_intrinsics.o
