Previously, the only thing we had was nir_src_as_const_value which returns a pointer to a nir_const_value which was NULL if the source wasn't actually a constant. This was great except that almost none of the users considered anything other than 32-bit values. With 8, 16, and 64-bit values floating around, we really shouldn't be hand-rolling it everywhere. Most of the code is currently safe if you operate under the assumption that things like array indices are always 32 bits. The glaring exception was some of the helpers in nir_search_helpers.h where we definitely cannot be making that assumption but were anyway.
I've converted core NIR and i965 but have not written patches for vc4, ir3, or radeon.
