SI-1786 incorporate defined bounds in inference
Also fixes SI-5459.
Look, you don't have to redeclare the bounds, isn't it exciting?
For instance, there are eight places in JavaMirrors with this:
jTypeVariable[_ <: GenericDeclaration]
After this code is in starr, those can look like this:
jTypeVariable[_]
Since TypeVariable's definition looks like this:
interface TypeVariable<D extends GenericDeclaration>
We already know that!
