    Description

      Implement ConstantDynamic with required hotspot and JDK changes supporting the existing arity and varargs patterns specified for the invocation of bootstrap methods.

      ldc instructions and bootstrap method arguments can reference a ConstantDynamic entry in the constant pool.

      The HotSpot implementation may include the ability to push arguments but this functionality will be disabled (behind a HotSpot flag) and will not be exposed via a public API (see JDK-8186210). Such an approach makes it easier manage the HotSpot changes.
