[PATCH] D143593: [InstCombine] Don't fold freeze poison when it's used in shufflevector

[Manuel Brito via Phabricator via llvm-commits]

ManuelJBrito added a comment.

Alternatively I was thinking of moving this match into getUndefReplacement and let it be a case where the undef replacement does no replacing.
After reading the discussion here [https://reviews.llvm.org/D123962], I think this makes this change cleaner and conceptually more sound.
Would this make sense?
