Add temporary workaround to support intersection-type targets on lambdas method references.
Type-checking code will now use the _first_ interface bound of an intersection type as the target type for lambdas/method refs.
This allows code using patterns such as:

(Predicate<String> & Serializable)x->false

To compile and behave exactly like before: additional interface bounds are simply ignored.
