[PATCH] D75385: [TargetLowering] Avoid infinite iteration on setcc fold

[David Greene via Phabricator via llvm-commits]

greened added a comment.

This appeared using a quite old version of LLVM using an out-of-tree target and I'm having trouble getting a valid testcase out that runs with the latest LLVM/bugpoint.  The code in question is exacly the same in the old and current LLVM so the bug still exists currently but I haven't yet been able to generate a testcase.  Thought I would at least put this up for review.  I'm not entirely confident current master could get into this situation but it seems wise to guard against it.
