Get stack adjustment from push operand in pushsf splitter

pushsf for -m64/-mx32 looks like

(set (mem:SF (pre_modify:SI (reg/f:SI 7 sp)
    (plus:SI (reg/f:SI 7 sp)
    (const_int -8))))
     (reg:SF 22 xmm1 [orig:84 D.1790 ] [84]))

Stack adjustment is in push operand and it isn't stack register mode size
which may be 4 bytes for -mx32.  This patch gets stack adjustment from
push operand if code of push isn't PRE_DEC.
