258a1e35e8 Improve support for non-virtual 'this' pointer adjustments. With this, it should be possible to use the new vtable layout code for all class hierarchies that do not involve virtual bases.

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.
