  Log Message:
  -----------
  PR50644: Do not warn on a declaration of `operator"" _foo`.

Also do not warn on `#define _foo` or `#undef _foo`.

Only global scope names starting with _[a-z] are reserved, not the use
of such an identifier in any other context.

  Log Message:
  -----------
  Add missing diagnostic for use of _reserved name in extern "C"
declaration.

Names starting with an underscore are reserved at the global scope, so
cannot be used as the name of an extern "C" symbol in any scope because
such usages conflict with a name at global scope.
