mono_jit_compile_method() returns a pointer to the native code and that
is cast to a function pointer and invoked directly.

        MonoObject *(*runtime_invoke) (MonoObject *this, void **params, MonoObject **exc);
	[...]
	runtime_invoke = mono_jit_compile_method (invoke);
	return runtime_invoke (obj, params, exc);
