compiler: add support for running a builtin in a goroutine

Not sure why you would ever do this, but it appears to be allowed by the
Go specification and previously TinyGo would crash with an unhelpful
error message when you would do this. I don't see any practical use of
it.

The implementation simply runs the builtin directly.
