PPC: [interpreter] Switch passing of new.target to register.

PPC: [interpreter] Switch passing of new.target to register.

Port 3d004eeab23c8b47bd9bdd2cc66434dcc19a1b2f

Original commit message:
    This passes the new.target value in a register instead of through a
    side-channel via the construct stub. The interpreter entry trampoline
    stores this value in a bytecode register so that it can be accessed
    directly by the interpreter. The size of the interpreter stack frame
    hence grows by one slot.
