2bd3c0fa34 Do not include the 'this' pointer adjustment in the covariant return type. Instead, store it in the (now oddly named) Thunks map.

6445773279 It is common for vtables to contain pointers to functions that have either incomplete return types or incomplete argument types. 
Handle this by returning the llvm::OpaqueType for those cases, which CodeGenModule::GetOrCreateLLVMFunction knows about, and treats as being an "incomplete function".

e128dd18ab IRgen: Switch the C++ mangler interfaces to take the SmallVector to write into, 
instead of requiring clients to make a raw_svector_ostream, which is just an
implementation detail.

aa51ad6815 Refine vtable, rtti and rtti name instantiation so that they follow 
the key function.  All the code is wired up, but won't work yet, as I
had to turn off key function calculation as it doesn't work yet.

Also, we refine visibility of the vtable, rtti and rtti name to match
the class, as well as as arrange for all the symbols to be internal
for anonymous namespace entities.

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!

2cefe38365 Fix the offset calculations for non-virtual bases with overrides.
