Reapply r69771, with updates & fixes:
...
Rework the shadow struct that is layed out for Objective-C classes.
- Superclasses are now always laid out in their shadow structure at
the first field.
- Prior to this, the entire class heirarchy was flattened into a
single structure which meant that alignment, padding, and bitfields
were incorrect (the ASTRecordLayout was correct however, which
meant our debug info didn't coincide with ivar offsets, for
example).
- This is still very suboptimal (for example, ivar are looked up
recursively, but I believe the ivar layout itself is now at least
close to correct.

Don't convert interface types (to structs) as part of CodeGenTypes.
...
- This has pros and cons, but for now the pros seem to significantly
outway the con.
The con is that we will always need to cast in the runtime
implementation to a struct type, if we wish to access an interface
directly.
The pros are:
- Avoid the cost of generating types which are used. Most
manipulation of Objective-C objects is done through messages, and
only the implementation of a class will directly access
memory. Previously, we would convert the type even if it only
appear as a function parameter, for example.
- We don't need to worry about incomplete types, and
UpdateCompletedType for interfaces is gone.
- It becomes easier to narrow the interface to the shadow struct for
Objective-C interfaces (so it can be eliminated).
Currently the runtimes still use the CodeGenTypes machinery to
generate the LLVM structure they need via ConvertTagDecl, but this can
eventually be replaced.
