[PATCH] D25299: Add StringRef::find_lower and contains_lower

Actually I don't see why we shouldn't just use `startswith_lower`.  It basically does exactly what you're saying.  Updated the code to use this approach.  While I'm in here, I think we might as well add `rfind_lower` to maintain API symmetry, so I went ahead and did that too.
