The only type that isn't an integer, isn't floating point, and isn't a vector; ladies and gentlemen, the gift that keeps on giving: x86_mmx! Fixes PR23246. Original message (reverted in r235062): [CodeGen] Combine concat_vectors of scalars into build_vector. Combine something like: (v8i8 concat_vectors (v2i8 bitcast (i16)) x4) into: (v8i8 (bitcast (v4i16 BUILD_VECTOR (i16) x4))) If any of the scalars are floating point, use that throughout.
