PPC: [runtime] Rewrite Function.prototype.toString in C++.

PPC: [runtime] Rewrite Function.prototype.toString in C++.

Port 4acca53e62cdfe6f3c495c87ca7d3c8fe1059f01

Original commit message:
    There's actually no point trying to do Function.prototype.toString in
    JavaScript, as it always calls into C++ at least once, so it only
    complicates things (esp. once we start optimizing bound functions).

    Drive-by-fix: Rename FunctionApply and FunctionCall builtins to also
    reflect the fact that these are builtins in the Function.prototype and
    not on Function itself.
