i386.md (Load+RegOp to Mov+MemOp peephole2): Use SWI mode iterator.

	* config/i386/i386.md (Load+RegOp to Mov+MemOp peephole2):
	Use SWI mode iterator.  Use general_reg_operand predicate.
	(Load+RegOp to Mov+MemOp peephole2 with vector regs): Split
	peephole to MMX and SSE part.  Use mmx_reg_operand and sse_reg_operand
	predicates.
