RFR 8043232: Index selection of overloaded java new constructors

[Attila Szegedi]

Two remarks:

1. in DynamicMethodLinker.java, you could factor out the 

             return new GuardedInvocation(MethodHandles.dropArguments(invocation, 0,
                     desc.getMethodType().parameterType(0)), Guards.getIdentityGuard(receiver));

part that is appearing in both if and else branch to be outside of the if, guarded with if(invocation == null) (maybe adding an assert invocation != null in the constructor (else) branch if it must not be null in that case (as you aren't testing for it being null there).

2. OverloadedDynamicMethod could save the boolean flag by returning methods.getFirst().isConstructor(). Maybe assert in the OverloadedDynamicMethod constructor that all elements of "methods" return the same value for isConstructor().

Other than these, +1.

Attila.
