[PATCH] D18905: [ValueTracking] Improve isImpliedCondition for conditions with matching operands.

[Chad Rosier via llvm-commits]

mcrosier updated this revision to Diff 53753.
mcrosier added a comment.

Address Sanjoy's feedback by:
-Renaming predicates that are unconditionally converted to unsigned predicate.
-Add a check to make sure we're never comparing predicates of different signs (with associated test case).
