Adding the new enumerator forced a bunch more changes into this patch than I would have liked. The -Wtautological-compare warning was extended to properly check the new comparison operator, clang-format needed updating because it uses precedence levels as weights for determining where to break lines (and several operators increased their precedence levels with this change), thread-safety analysis needed changes to build its own IL properly for the new operator. All "real" semantic checking for this operator has been deferred to a future patch. For now, we use the relational comparison rules and arbitrarily give the builtin form of the operator a return type of 'void'. llvm-svn: 320707
