[PATCH] D56802: [CodeGenObjC] Treat ivar offsets variables as constant if they refer to ivars of a direct subclass of NSObject with an @implementation

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Emitting the global as `const` is probably still a good idea; if the global actually gets mapped as a constant, we'll end up making a dynamic assertion that we got the offset right.  It's possible that the section will inhibit that, though.
