5404 (c_common_init): Update accordingly.
5405 (push_command_line_include): Don't cpp_push_main_file.
5406 Do LC_RENAME rather than LC_LEASE to get back to main file.
5407 Compared to pre-10-01 version, inline cpp_rename_to_main_file.
5408 (c_common_parse_file): Call cpp_read_main_file for subsequent main
5409 files, but call finish_options for all files.
5410 * c-opts.c (sanitize_cpp_opts): Don't set cpp_opts->working_directory.
5411 * fix-header.c (read_scan_file): Call cpp_read_main_file instead of
5412 cpp_find_main_file + cpp_push_main_file.
5413 * c-lex.c (fe_file_change): Don't set main_input_filename here.
