(recog_memoized): New macro.
* rtl.h (single_set): Rename to single_set_1
(single_set): New macro.

Do not use match_dup of input operands at outputs.
Use register_operand for memory expression.
(rep_movsi): Put use last, canonicalize.
Use register_operand for memory expression.
(rep_movqi): Put use last.
Use register_operand for memory expression.
