[PATCH] D150226: [Clang] Remove ability to downgrade warning on the diagnostic for setting a non fixed enum to a value outside the range of the enumeration values

I guess to make that work, the constant evaluator would need to track whether we're in an SFINAE context (Sema::isSFINAEContext()). Based on that, we'd need to explicitly generate an error if we're in an SFINAE context, and a warning if we're not in such a context.
