[PATCH] D39726: [X86] Attempt to match multiple binary reduction ops at once. NFCI

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon created this revision.

matchBinOpReduction currently matches against a single opcode, but we already have a case where we try to match against AND/OR and I'll be shortly adding another case  for SMAX/SMIN/UMAX/UMIN.

This NFCI patch alters matchBinOpReduction to try and pattern match against any of the provided list of candidate bin ops at once to save time.
