Review request for JDK-8167037: Remove CALL_METHOD support from internal Nashorn linkers

[Attila Szegedi]

Please review JDK-8167037 "Remove CALL_METHOD support from internal Nashorn linkers" at <http://cr.openjdk.java.net/~attila/8167037/webrev.jdk9> for <https://bugs.openjdk.java.net/browse/JDK-8167037>

Nashorn never emits CALL_METHOD Dynalink operation; therefore code for supporting it in internal linkers (those that only service call sites in Nashorn-generated bytecode) is unnecessary. 

I originally stumbled upon this inspecting ScriptObject.findCallMethodMethod() and noticed that the code was even somewhat incorrect by weakening the lookup of the call to public lookup. Thinking of fixing it, I realized it's actually never used.

Thanks,
  Attila.
