Florian Hahn 98f11a7d75 [SCEV] Handle case where MaxBECount is less precise than ExactBECount for OR. ... In some cases, MaxBECount can be less precise than ExactBECount for AND and OR (the AND case was PR26207). In the OR test case, both ExactBECounts are undef, but MaxBECount are different, so we hit the assertion below. This patch uses the same solution the AND case already uses. Assertion failed: ((isa<SCEVCouldNotCompute>(ExactNotTaken) || !isa<SCEVCouldNotCompute>(MaxNotTaken)) && "Exact is not allowed to be less precise than Max"), function ExitLimit This patch also consolidates test cases for both AND and OR in a single test case.
