This task tracks a second phase of updates to java.lang.invoke.

As things currently stand, we have the following in jake:
- access checks updated to respect module boundaries
- new lookup mode bit for modules
- Lookup.in changes to drop access when teleporting to a named module
- publicLookup changed so that the lookup class is in an unnamed module

This needs to be revisited to take account of feedback and ideas from John.

Other possible changes are:

- improving IllegalAccessException messages
- testFindVirtualClone0
- LogGeneratedClassesTest when running on an exploded build
