[PATCH] D93818: [LangRef] Update shufflevector's semantics to return poison if the mask is undef

[Juneyoung Lee via Phabricator via llvm-commits]

aqjune added a comment.

This patch was blocked by the old problematic select -> and/or folding, which is gone.
I'll restart pushing this patch as well as relevant ones (D94380 <https://reviews.llvm.org/D94380>, D93817 <https://reviews.llvm.org/D93817>).
