[4/10] debug-early merge: Fortran front-end

gcc/fortran/

	* f95-lang.c (gfc_write_global_declarations): Remove.
	(LANG_HOOKS_WRITE_GLOBALS): Remove.
	(gfc_write_global_declarations): Move code from here to...
	(gfc_be_parse_file): ...here.
	Call global_decl_processing.
	* trans-decl.c (gfc_emit_parameter_debug_info): Rename global_decl
	to early_global_decl.
