fb4dda4fed Instead of storing CXXMethodDecls in the vtable builder, store GlobalDecls so we can represent both the complete and deleting destructors. Also, when encountering a destructor decl, emit entries for both the complete and deleting destructors. Mike, please review. 
With this change, FileCheck builds and runs the clang test suite without failures!

fa81808a11 Refine construction vtables; they don't include bits that don't have 
virtual bases unless they are morally virtual.

b21c4eede4 Shift the vcall slots for non-virtual bases of a virtual base, up into 
the virtual base so they can be reused properly.  Don't reuse vcall
slots across a virtual boundary.  WIP.  I have a testcase, but there
are still things that need to be fixed before the testcase can go in.
