re PR ipa/63566 (i686 bootstrap fails: ICE RTL flag check: INSN_UID used with unexpected rtx code 'set' in INSN_UID, at rtl.h:1326)

	PR ipa/63566 
	* i386.c (ix86_function_regparm): Look through aliases to see if callee
	is local and optimized.
	(ix86_function_sseregparm): Likewise; also use target's SSE math
	settings; error out instead of silently generating wrong code
	on mismatches.
	(init_cumulative_args): Look through aliases.
