[PATCH] Use vm in sse2_cvtps2pd

[H.J. Lu]

sse2_cvtps2pd<mask_name> has

(define_insn "sse2_cvtps2pd<mask_name>"
  [(set (match_operand:V2DF 0 "register_operand" "=v") 
        (float_extend:V2DF
          (vec_select:V2SF
            (match_operand:V4SF 1 "vector_operand" "vBm") 
            (parallel [(const_int 0) (const_int 1)]))))]

The memory operand size is 8 bytes (2 floats).  We should use vm instead
of vBm.  Tested on Linux/x86-64.  OK for trunk?
