Alternate lambda metafactory

The language runtime needs to be enhanced with an alternate metafactory which can inject additional marker interfaces. Its signature and behavior is described below:

    /**
     * Alternate meta-factory for conversion of lambda expressions or method references to functional interfaces,
     * which supports serialization and other uncommon options.
     *
     * @param caller Stacked automatically by VM; represents a lookup context with the accessibility privileges
     * of the caller.
     * @param invokedName Stacked automatically by VM; the name of the invoked method as it appears at the call site.
     * Currently unused.
     * @param invokedType Stacked automatically by VM; the signature of the invoked method, which includes the
     * expected static type of the returned lambda object, and the static types of the captured
     * arguments for the lambda. In the event that the implementation method is an instance method,
     * the first argument in the invocation signature will correspond to the receiver.
     * @param samMethod The primary method in the functional interface to which the lambda or method reference is
     * being converted, represented as a method handle.
     * @param implMethod The implementation method which should be called (with suitable adaptation of argument
     * types, return types, and adjustment for captured arguments) when methods of the resulting
     * functional interface instance are invoked.
     * @param instantiatedMethodType The signature of the SAM method from the functional interface's perspective
     * @param flags A bitmask containing flags that may influence the translation of this lambda expression. Defined
     * fields include FLAG_SERIALIZABLE.
     * @param markerInterfaces Additional interfaces which the lambda object should implement.
     * @return a CallSite, which, when invoked, will return an instance of the functional interface
     * @throws ReflectiveOperationException
     * @throws LambdaConversionException If any of the meta-factory protocol invariants are violated
