PPC: [runtime] Introduce FastNewStrictArgumentsStub to optimize strict arguments.

PPC: [runtime] Introduce FastNewStrictArgumentsStub to optimize strict arguments.

Port 09d845354742a90fc0596262eb5cbaac169e5ed9

Original commit message:
    The FastNewStrictArgumentsStub is very similar to the recently added
    FastNewRestParameterStub, it's actually almost a copy of it, except that
    it doesn't have the fast case we have for the empty rest parameter. This
    patch improves strict arguments in TurboFan and fullcodegen by up to 10x
    compared to the previous version.

    Also introduce proper JSSloppyArgumentsObject and JSStrictArgumentsObject
    for the in-object properties instead of having them as constants in the
    Heap class.

    Drive-by-fix: Use this stub and the FastNewRestParameterStub in the
    interpreter to avoid the runtime call overhead for strict arguments
    and rest parameter creation.
