[PATCH] D88750: [GlobalISel] Add G_VECREDUCE_* opcodes for vector reductions

[Amara Emerson via Phabricator via llvm-commits]

@arsenm Note: the ops defined in this patch differ a bit from the SelectionDAG ones. For GlobalISel I kept the scalar accumulator that the fadd/fmul have for the opcode too. SDAG breaks these apart into the reduction and a separate fadd/fmul op. Not clear to me yet if there's a significant advantage either way.
