[PATCH] D25200: [InstCombine] New opportunities for FoldAndOfICmp and FoldXorOfICmp

[Ehsan Amiri via llvm-commits]

amehsan created this revision.
amehsan added reviewers: majnemer, spatel.
amehsan added a subscriber: llvm-commits.

This is motivated by PR-30483. New testcases and comments in the code explain the opportunities. Still more work can be done for this. I will open new PR for remaining cases (including those that Sanjay mentioned in the PR 30483)
