David Stenberg 0af67e5b65 [SimplifyCFG] Fix a debug invariant bug in FoldBranchToCommonDest() 
Summary:
Fix a case where FoldBranchToCommonDest() would bail out from doing CSE
when encountering a debug intrinsic. Handle that by skipping past the
debug intrinsics.

Also, as a minor refactoring, rename checkCSEInPredecessor() to
tryCSEWithPredecessor() to make it a bit more clear that the function
may remove instructions.
