PPC: [ic] Change CompareIC to handle JSReceiver instead of JSObject.

Port 0ed0878041574382b75d4d549f3ff73afcc72efb

Original commit message:
    There's no reason to limit the CompareIC to (known) JSObject instances,
    as all JSReceivers behave the same wrt. abstract and strict equality.
    So remove this historical limitation and track JSReceivers instead.
