PPC: Make Simulator respect C stack limits as well.

PPC: Make Simulator respect C stack limits as well.

Port 7fb31bdba4f2a0320507956a085f083d76bce48c

Original commit message:
    The simulator uses a separate JS stack, exhaustion of the C stack
    however is not caught by JS limit checks. This change now lowers the
    limit of the JS stack accordingly on function calls.
