[PowerPC] PR20280 - Slots for byval parameters are not immutable

Found by inspection while looking at PR20280: code would mark slots
in the parameter save area where a byval parameter is passed as
"immutable".  This is not correct since code is allowed to modify
byval parameters in place in the parameter save area.
