	personality hook.

	* config/ia64/ia64.c (ia64_asm_emit_except_personality,
	ia64_asm_init_sections, TARGET_ASM_EMIT_EXCEPT_PERSONALITY,
	TARGET_ASM_INIT_SECTIONS): New.
	(ia64_asm_unwind_emit): Rename from process_for_unwind_directive,
	make static.
	(TARGET_ASM_UNWIND_EMIT): Update to match.
	* config/ia64/ia64-protos.h (process_for_unwind_directive): Remove.

	* config/arm/arm.c (arm_asm_emit_except_personality): New.
