Justin Bogner e318ce611f ScalarEvolution: Fix handling of AddRecs in isKnownPredicate ... ScalarEvolution::isKnownPredicate() can wrongly reduce a comparison when both the LHS and RHS are SCEVAddRecExprs. This checks that both LHS and RHS are guarded in the case when both are SCEVAddRecExprs. The test case is against indvars because I could not find a way to directly test SCEV.
