Twine.h says twines should only be accepted as const references in arguments, but there are a bunch of functions that take Twine by value (e.g. you'll find lots of them in CGObjCMac.cpp in clang). Is this just a potential performance issue, or are there potential correctness issues from passing a twine by value as well?
