Log:
        PR fortran/25324
        * Make-lang.in (fortran/scanner.o): Depend on toplev.h.
        * lang.opt (fpreprocessed): New option.
        * scanner.c: Include toplev.h.
        (gfc_src_file, gfc_src_preprocessor_lines): New variables.
        (preprocessor_line): Unescape filename if there were any
        backslashes.
        (load_file): If initial and gfc_src_file is not NULL,
        use it rather than opening the file.  If gfc_src_preprocessor_lines
        has non-NULL elements, pass it to preprocessor_line.
        (unescape_filename, gfc_read_orig_filename): New functions.
        * gfortran.h (gfc_option_t): Add flag_preprocessed.
        (gfc_read_orig_filename): New prototype.
        * options.c (gfc_init_options): Clear flag_preprocessed.
        (gfc_post_options): If flag_preprocessed, call
        gfc_read_orig_filename.
        (gfc_handle_option): Handle OPT_fpreprocessed.
        * lang-specs.h: Pass -fpreprocessed to f951 if preprocessing
        sources.
