re PR other/44034 (target hooks are hard to maintain)

gcc:
	PR other/44034
	* target.def, doc/tm.texi.in, genhooks.c: New files.
	* target.h: Instead of defining individual hook members,
	define DEFHOOKPOD / DEFHOOK / DEFHOOK_UNDOC / HOOKSTRUCT and
	include target.def.
	* target-def.h: Instead of defining individual hook initializers,
	include target-hooks-def.h.
	* df-scan.c, haifa-sched.c, sel-sched.c: Rename targetm members:
	targetm.live_on_entry -> targetm.extra_live_on_entry
	targetm.sched.md_finish ->targetm.sched.finish
	targetm.sched.md_init -> targetm.sched.init
	targetm.sched.md_init_global -> targetm.sched.init_global
	targetm.asm_out.unwind_label -> targetm.asm_out.emit_unwind_label
	targetm.asm_out.except_table_label ->
	  targetm.asm_out.emit_except_table_label
	targetm.asm_out.visibility -> targetm.asm_out.assemble_visibility
	targetm.target_help -> targetm.help
	targetm.vectorize.builtin_support_vector_misalignment ->
	  targetm.vectorize.support_vector_misalignment
	targetm.file_start_app_off -> targetm.asm_file_start_app_off
	targetm.file_start_file_directive ->
	 targetm.asm_file_start_file_directive
	* dwarf2out.c, opts.c, tree-vect-data-refs.c, except.c: Likewise.
	* varasm.c, config/alpha/alpha.c, config/cris/cris.c: Likewise.
	* gcc/config/spu/spu.c, config/ia64/ia64.c: Rename target macros:
	TARGET_VECTOR_ALIGNMENT_REACHABLE ->
	  TARGET_VECTORIZE_VECTOR_ALIGNMENT_REACHABLE
	TARGET_SUPPORT_VECTOR_MISALIGNMENT ->
	  TARGET_VECTORIZE_SUPPORT_VECTOR_MISALIGNMENT
	TARGET_UNWIND_EMIT -> TARGET_ASM_UNWIND_EMIT
	* config/rs6000/rs6000.c, config/arm/arm.c: Likewise.
	* Makefile.in (TARGET_H): Depend on target.def.
	(TARGET_DEF_H): Depend on target-hooks-def.h.
	(target-hooks-def.h, tm.texi, s-target-hooks-def-h): New rules.
	(s-tm-texi, build/genhooks.o, build/genhooks): Likewise.
	* doc/tm.texi: Regenerate.
gcc/c-family:
	* c-common.c: Rename targetm member:
	targetm.enum_va_list -> targetm.enum_va_list_p
gcc/po:
	* EXCLUDES: Add genhooks.c.
