Fix PPC redirectors.

Our old redirectors were emitting code to call their target functions normally.
However, the PPC ABI expects callers to set up parameter save areas for their
callees, notably if the target is a varargs function.

Instead, mimic the pattern used when calling an external function or function
pointer and avoid touching the stack.
