AFAIK, internal errors are reported using the internal_error
or internal_error_no_backtrace APIs.

Would using the existing internal_error{,no_backtrace}, and
sorry work for this? (I.e., not translating those.)  If my
count is right there are nearly 500 calls to these three in
GCC sources so I'm not sure that would put enough of a dent
in the 12K messages to translate but I'm even less sure that
adding yet another API would do even that much.

There are 20-some-odd functions to report diagnostics in GCC
(counting those in diagnostic-core.h).  I haven't used them all
or even understand all their differences and use cases yet so
I would rather no add more to the list if it can be helped.
