nir: Generalize nir_intrinsic_vote_eq
The SPIR-V extension wants us to be able to do an AllEqual on any vector
or scalar type. This has two implications:
1) We need to be able to handle vectors so we switch the vote_eq
intrinsics to be vectorized intrinsics.
2) We need to handle floats which have different behavior with respect
to +-0, NaN, etc. than the integer variant so we need two variants.
