[PATCH] D106222: [X86] Don't use known bits to simplify shuffles.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

OK, I'll put together a patch updating the comments.

I think this patch gets to the real problem (although there might be other similar issues) and helps us avoid the avoidable nasty regressions from D106053 <https://reviews.llvm.org/D106053> - does anyone else have any thoughts?
