fixes: Use a separate register, instead of SP, as the
calling-convention resource, to avoid spurious conflicts with
actual uses of SP. Also, fix unscheduling of calling sequences,

If the register class in the source alias is a subclass of the register class
of the actual instruction, the alias can still match OK since the constraints
