Check in the beginnings of my new vtable layout builder idea.
Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code.
I've also added a very simple new vtable layout test case.
