[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. llvm-svn: 317592
