03db9e9cd3 Correctly calculate base offsets for 'this' pointer adjustments involving virtual bases. This can't be tested yet due to lack of vcall offsets :)

ef3057c419 Switch the standard DeclarationName comparator to be a tri-valued comparator. 
Use that while fixing a nasty misuse of qsort in vtable codegen which, somehow,
has not actually caused a crash.

5d40c6f658 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.
