Log Message:
lint: report proper file name in assertion failures

When given the (obviously malformed) translation unit 'f=({;};}', lint
runs into an assertion failure.  It reported this as occurring near
':1'.  This location was missing a filename since the input didn't
contain a GCC line number directive such as '# 2 "input.c"'.  In GCC mode,
the GCC builtins are loaded first, in which case the reported location
was ':9'.

Fix this by providing proper location information, even for input that
does not come from the GCC C preprocessor.
