Log:
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.
