Andrea Di Biagio 26cba06d11 [X86] Avoid emitting unnecessary test instructions. ... This patch teaches the backend how to check for the 'NoSignedWrap' flag on binary operations to improve the emission of 'test' instructions. If the result of a binary operation is known not to overflow we know that resetting the Overflow flag is unnecessary and so we can avoid emitting the test instruction.
