[PATCH] D124119: [InstCombine] Combine instructions of type or/and where AND masks can be combined.

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

IIUC, the problem/fix (and it would be good to put something like this in the updated commit message for easier reference):
The previous revision/commit did not check one-use of an intermediate value that this transform re-uses. When that value has another use, an existing transform will try to invert the transform here. By adding one-use checks, we avoid the infinite loops seen with the earlier commit.
