PPC: [crankshaft] Deoptimize if HHasInPrototypeChainAndBranch hits a proxy.

Port a330af0ed1f237ba17ac2242ce16cad5616c0597

Original commit message:
    The optimized code generated by Crankshaft cannot properly deal
    with proxies (in the prototype chain), and there's probably no
    point in trying to make that work^Wfast with Crankshaft at all.
    TurboFan will handle that properly; Crankshaft just bails out
    to fullcodegen, which then goes to the runtime, which should do
    the right thing soon.
