[Hexagon] Make a test more flexible in HexagonLoopIdiomRecognition An "or" that sets the sign-bit can be replaced with a "xor", if the sign-bit was known to be clear before. With some changes to instruction combining, the simple sign-bit check was failing. Replace it with a more flexible one to catch more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@317592 91177308-0d34-0410-b5e6-96231b3b80d8
