Remove separate flags for class and metaclass.
...
Every class is either a class or a metaclass, it doesn't make sense to
use two flags to store one bit of data.
Also remove the newabi flag from classes in the v2 ABI, where it's
redundant.

Audit the runtime for direct access to variable-sized arrays.
...
Several of the structures now end with an array of structures that may
have other fields added to them that the runtime doesn't know about yet
by a compiler. Rather than indexing into them directly, we must call an
accessor to find the correct address.
A few of the places where accesses were replaced were in functions where
it is safe because they only deal with versions of the structures that
are dynamically allocated (and will therefore have the correct size).
This was done to simplify future auditing: these fields should be
accessed directly only from the accessor functions in the header and
from the upgraders (currently in legacy.c).
Also fix a few bugs where the sizes weren't being filled in.

Add support for improved property structure.
...
As a side effect, we need to upgrade properties in class and protocols
(but not categories because we didn't have class properties in earlier
ABIs).

Treat the property encoding string as canonical.

This is more reliable than the bitfields (and is constructed from them if the compiler doesn’t fill in the string).

Small cleanup. Use the ARC functions for retain / release / autorelease messages everywhere. This will make properties faster if we're using an ARC-compatible NSObject.

Changed ptrdiff_t to int in property accessors. This is for compatibility with some changes in clang that are required to prevent things from breaking on LP64 platforms.
...
It would be cleaner to use a ptrdiff_t here, but unfortunately we can't because the ivar_offset field in the runtime metadata is an int so ivar offsets beyond 4GB will not work on LP64 platforms.
This probably isn't a limitation. If you have more than 4GB of ivars in one object, you've done something badly wrong and probably shouldn't be allowed to write code anymore.
