[RISCV] Reserve an emergency spill slot for the register scavenger when necessary

Although the register scavenger can often find a spare register, an emergency 
spill slot is needed to guarantee success. Reserve this slot in cases where 
the function is known to have a large stack (meaning the scavenger may be 
needed when forming stack addresses).
