	argument.  Update all uses.
	* config/i386/i386.c (memory_address_length): If not LEA insn, then
	add length of addr32 prefix based on mode of base or index register.
	(ix86_attr_length_address_default) <TYPE_LEA>: Do not handle SImode
	addresses here.  Update call to memory_address_length.
	(ix86_print_address_operand): Use SImode_address_operand predicate.
	* config/i386/predicates.md (SImode_address_operand): New.
	* config/i386/i386.md (lea<mode>): Use SImode_address_operand
	to calculate "mode" attribute.  Use SImode_address_operand predicate
	instead of open-coding accepted RTX codes.
