[PATCH] D158068: [DAG] FoldSetCC - add missing icmp(X,undef) -> isTrueWhenEqual case

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

It was requested by @craig.topper for an upcoming patch - he noticed that D59363 <https://reviews.llvm.org/D59363> had mentioned undef handling in the comments and hadn't implemented it.
