84e46aa6 - [X86] combineConcatVectorOps - add handling to concat setcc instructions together (#170295)

[X86] combineConcatVectorOps - add handling to concat setcc instructions together (#170295) So far this only handles AVX512 predicate masks, which is by far the easiest to support - AVX1/AVX2 support can mostly be dealt with via CMPP + CMPEQ/GT nodes (but these still fail for some icmp expansions where nodes have multiple uses).
