* toplev.c (output_lang_identify): Delete.

	(compile_file): Don't call ASM_IDENTIFY_GCC or ASM_IDENTIFY_LANGUAGE.
	Don't generate gcc2_compiled. label.  Don't emit a nop if profiling.
	If IDENT_ASM_OP is defined, emit an .ident "GCC (GNU) <version>"
	after calling ASM_FILE_END.

	* dbxout.c (dbxout_init): Don't call ASM_IDENTIFY_GCC_AFTER_SOURCE.
	Instead, unconditionally emit an N_OPT stab with string equal
	to STABS_GCC_MARKER, which defaults to "gcc2_compiled."

	* defaults.h: Don't provide default for ASM_IDENTIFY_LANGUAGE.
