Sanjay Patel 73f8eff19e Add a convenience method to copy wrapping, exact, and fast-math flags (NFC). ... The loop vectorizer preserves wrapping, exact, and fast-math properties of scalar instructions. This patch adds a convenience method to make that operation easier because we need to do this in the loop vectorizer, SLP vectorizer, and possibly other places. Although this is a 'no functional change' patch, I've added a testcase to verify that the exact flag is preserved by the loop vectorizer. The wrapping and fast-math flags are already checked in existing testcases.
