[PATCH] D56355: [InstCombine] Simplify cttz/ctlz + icmp ugt/ult into mask check

[Nikita Popov via Phabricator via llvm-commits]

nikic updated this revision to Diff 180378.
nikic added a comment.

Create new compare instructions instead of modifying existing ones and manually managing worklist.

I'll also update the existing code for intrinsic icmps to this style, if it's accepted in this form.
