* [NewGVN] Don't derive incorrect implications.Davide Italiano2017-05-011-0/+24
In the testcase attached, we believe %tmp1 implies %tmp4. where: br i1 %tmp1, label %bb2, label %bb7 br i1 %tmp4, label %bb5, label %bb7 because Wwhile looking at PredicateInfo stuffs we end up calling isImpliedTrueByMatchingCmp() with the arguments backwards.
