[PATCH] D34006: [LoopSimplify] Add opt-bisect support to LoopSimplify pass

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

I don't we use this as a standalone pass in trunk, rather we always use the utility function entry point that can be called from other passes.  It is also usable as a pass from the command line though.  Our internal codebase does use it as a standalone pass though. But currently it doesn't participate in opt-bisect so it can create changes to the CFG while trying to bisect.

This patch adds the skipFunction call so that it will partcipate.
