Hi,

currently, the call to begin_epilogue debug hook in final_scan_insn is unconditional and therefore occurs even when DECL_IGNORED_P is true.  This is not what is done for other debug hooks, and leads to ICE on VMS (the only platform that defines the hook) as last_filename is NULL.

Tested on alpha64-dec-openvms,
committed to trunk as obvious.

Tristan.

	* final.c (final_scan_insn): Guard the call to begin_epilogue
	debug hook.
