Fix ia64-linux kernel miscompile, bad unwind info when reorder epilogue block.
* final.c (final_scan_insn, case NOTE_INSN_BASIC_BLOCK): Call
IA64_UNWIND_EMIT.
* config/ia64/ia64.c (block_num, need_copy_state): New static vars.
(process_epilogue): New static function.
(process_set): Call process_epilogue instead of emitting .restore
directly.
(process_for_unwind_directive): Handle NOTE_INSN_BASIC_BLOCK.
