Ok, I think I've gotten it to work by doing this:

MethodHandles.convertArguments(guardWithTest, site.type())

But I expected guardWithTest to propagate the method type of the 
target/fallback all the way through. Is that incorrect?

With this change the following gWT dispatch code appears to be functional!

I still have to run -Xint, since I presume JIT isn't wired yet. I'm 
going to hook up other call paths and add in the additional missing 
logic for method_missing and report back.
