[crankshaft] Deoptimize if HHasInPrototypeChainAndBranch hits a proxy.

[crankshaft] Deoptimize if HHasInPrototypeChainAndBranch hits a proxy.

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.

Hey Yang,

Easy fix to make Crankshaft bailout on proxies.
Please take a look.

Thanks,
 Benedikt
