> This patch reduces work done initializing VarForms - mostly observed when loading each VarHandle implementation class.
> - Lazily resolve MemberNames.
> - Streamline MethodType creation. This reduces the number of MethodTypes created. 
> Net effect is a reduction in bytecode executed per VH class by 50-60%.
