rtl.def: Wrap MD-only codes in #ifdef GENERATOR_FILE.

	* rtl.def: Wrap MD-only codes in #ifdef GENERATOR_FILE.
	* gengtype.c: Don't include rtl.h.  Define enum rtx_code and
	rtx_name, rtx_format arrays by direct reference to rtl.def,
	first undefining GENERATOR_FILE.  Define enum insn_note and
	note_insn_name array by direct reference to insn-notes.def.
	(adjust_field_rtx_def): Remove local definition of rtx_name.
	Use symbolic names for insn notes.
	* Makefile.in (gengtype.o): Update dependencies.
