* gengtype-lex.l:  Temporary kludge to avoid duplicate typedef.
	* gengtype.c:  Update for now typdefs in input.h.  More kludges.
	* modulo-sched.c (sms_schedule):  Use NOTE_EXPANDED_LOCATION macro.
	* ra-debug.c (ra_print_rtl):  Likewise.
	* sched-rgn.c:  Likewise.
	* sched-vis.c:  Likewise.
	* rtl.h (gen_rtx_ASM_OPERANDS):  Redefine if USE_MAPPED_LOCATION.
	* stmt.c (expand_asm_operands):  Adjust calls to gen_rtx_ASM_OPERANDS.
	* tree-cfg.c:  Use new macros and typedefs.
	* tree-flow-inline.h:  Likewise.
