[PATCH] D122299: [InstCombine] Fix missing nsw flag when fold -(x-y) to y-x

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

I'm fine with abandoning the code change. I just wanted to make sure we were not miscompiling in D122013 <https://reviews.llvm.org/D122013>.

I would commit the tests anyway with some comments or a link back to this review (in case this comes up again in the future in some other context).
