I'm not sure, but the question led me to thinking about only asserting
if input_location != UNKNOWN_LOCATION. Would that work?
Ah, that would be a nice "implementation" of my vague idea! Thus, what
I'm going to test, in warning_at & co is something like:
gcc_assert (input_location == UNKNOWN_LOCATION
|| location != UNKNOWN_LOCATION);
