	* Makefile.in (TARGET_DEF): Add target-insns.def.
	(.PRECIOUS, simple_rtl_generated_h): Add insn-target-def.h.
	(build/gentarget-def.o): New rule.
	(genprogrtl): Add target-def.
	* target-insns.def, gentarget-def.c: New files.
	* target.def: Add targetm.have_* and targetm.gen_* hooks,
	based on the contents of target-insns.def.
	* defaults.h (HAVE_simple_return, gen_simple_return): Delete.
	(HAVE_return, gen_return): Delete.
	* target-def.h: Include insn-target-def.h.
	* cfgrtl.c (force_nonfallthru_and_redirect): Use targetm interface
	instead of direct calls.  Rely on them to do the appropriate assertions.
	* function.c (gen_return_pattern): Likewise.  Return an rtx_insn *.
	(convert_jumps_to_returns): Use targetm interface instead of
	direct calls.
	(thread_prologue_and_epilogue_insns): Likewise.
	* reorg.c (find_end_label, dbr_schedule): Likewise.
	* shrink-wrap.h (SHRINK_WRAPPING_ENABLED): Likewise.
	* shrink-wrap.c (convert_to_simple_return): Likewise.
	(try_shrink_wrapping): Use SHRINK_WRAPPING_ENABLED.
