rs6000: Fix stack clash for big residuals (PR85287)
The stack clash protection code had a logic error in how it decided
whether to put the final update size in a register, or to emit it
directly in an insn. This fixes it. It also tidies some surrounding
code.
PR target/85287
* gcc/config/rs6000/rs6000.md (allocate_stack): Put the residual size
for stack clash protection in a register whenever we need it to be in
a register.
