implement basic Java 8 lambda support The two big pieces here are basic invokedynamic support and a working version of LambdaMetaFactory.metafactory. The latter works by dynamically building a synthetic class with three methods: a static factory method, a constructor for the factory method to call, and a method to satisfy the requested interface which defers to the specified MethodHandle. This work relies heavily on Avian's specific MethodType and MethodHandle implementations, which provide extra, non-standard features to make code generation easier. That means we'll probably need to use Avian's versions of java.lang.invoke.* even when building with the OpenJDK or Android class libraries. 2015-08-05 21:55:52 +00:00			`private interface Operation {`
