    analyzer: log the stashing of named constants [PR107711]

    PR analyzer/107711 seems to be a bug in how named constants are looked =
up
    by the analyzer in the C frontend.

    To help debug this, this patch extends -fdump-analyzer and
    -fdump-analyzer-stderr so that they dump this part of the analyzer's
    startup.

    gcc/analyzer/ChangeLog:
            PR analyzer/107711
            * analyzer-language.cc: Include "diagnostic.h".
            (maybe_stash_named_constant): Add logger param and use it to log
            the name being looked up, and the result.
            (stash_named_constants): New, splitting out from...
            (on_finish_translation_unit): ...this function.  Call
            get_or_create_logfile and use the result to create a logger
            instance, passing it to stash_named_constants.
            * analyzer.h (get_or_create_any_logfile): New decl.
            * engine.cc (dump_fout, owns_dump_fout): New globals, split out
            from run_checkers.
            (get_or_create_any_logfile): New function, split out from...
            (run_checkers): ...here, so that the logfile can be opened by
            on_finish_translation_unit.  Clear the globals when closing the
            dump file.

    gcc/testsuite/ChangeLog:
            PR analyzer/107711
            * gcc.dg/analyzer/fdump-analyzer-1.c: New test.
