[Bug rtl-optimization/36998] [4.3/4.4 regression] Ada bootstrap broken on i586-*-*

pop.patch

Additional patch on top of sp=reg.patch patch, which should fix the SH4 case -
the simplistic stack_adjust_offset wouldn't see the adjustments in pop
instructions, only push instructions.  I'm not sure if it is enough to do it
this way, or whether for_each_rtx shouldn't be called instead to find all
embedded MEMs with {PRE,POST}_{INC,DEC,MODIFY} operands on sp register.
