Rework the shadow struct that is layed out for Objective-C classes.
- Superclasses are now always laid out 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
weren't packed correctly (the ASTRecordLayout was correct however,
which meant our debug info didn't coincide with ivar offsets, for
example).
- This is still very suboptimal, but I believe the ivar layout itself
is now at least close to correct.
- <rdar://problem/6773388> error: objc[29823]: layout bitmap sliding
backwards
