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

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

ping - neither the amdgpu or powerpc `switch undef` cases look to be necessary to fix (although it would have been nice if we could re-reduce them with this patch in place.....).
