[PATCH] Move class temp_source_file from input.c to selftest.c/h

[David Malcolm]

I have followup patches that use this class in selftests in various
places, so this patch moves it to selftest.h.

Successfully bootstrapped&regrtested on x86_64-pc-linux-gnu.

OK for trunk?

gcc/ChangeLog:
        * input.c (class selftest::temp_source_file): Move to
        selftest.h.
        (selftest::temp_source_file::temp_source_file): Move to
        selftest.c.
        (selftest::temp_source_file::~temp_source_file): Likewise.
        * selftest.c (selftest::temp_source_file::temp_source_file): Move
        here from input.c.
        (selftest::temp_source_file::~temp_source_file): Likewise.
        * selftest.h (class selftest::temp_source_file): Move here from
        input.c
