Change deprecated semantics of function template signatures.

This changes how FunctionTemplate interprets a Signature that specifies
compatible receivers and arguments. Only the hidden prototype chain will
be considered when searching for compatible receivers. This prevents
JavaScript from modifying the inheritance relationship set up by the
