[PATCH] D93586: [InstCombine] use poison as placeholder for undemanded elems

[Juneyoung Lee via Phabricator via cfe-commits]

aqjune added a comment.

There are 3 more patches:

https://reviews.llvm.org/D93793 (IRBuilder's CreateVectorSplat)
https://reviews.llvm.org/D93817 (Other transformations) 
https://reviews.llvm.org/D93818 (LangRef)

Would it be desirable if I land all of these at once as well as this (93586) when they are accepted, or is incrementally landing accepted patches okay?
