Summary: Missed in the original commit, use the correct callee-saved register list for spilling, instead of the standard SVR432 list. This avoids needlessly spilling the SPE non-volatile registers when they're not used. As part of this, also add where missing, and sort, the spill opcode checks for SPE and SPE4 register classes.
