GetHash and friends: return a raw pointer instead of Handle<Smi>

GetHash and friends: return a raw pointer instead of Handle<Smi>

In most cases we return a Smi and undefined for the other cases. Hence there
is no need to handlify the result unecessary. Additionally pass in the isolate
for the hash-symbol lookup.
