[PATCH] D122485: [SimplifyCFG] Fold mutil cases to And mask

[chenglin.bi via Phabricator via llvm-commits]

bcl5980 added a comment.

I have no too much confidence about this change, so this should be a scatch without detail comments and the magic number is also a rough value.
So can someone help to give me suggestion it is worth or not? Then I can continue work on it
