[PATCH] D31004: [Objective-C] Fix __weak type traits with -fobjc-weak

[Brian T. Kelley via Phabricator via cfe-commits]

bkelley created this revision.

Similar to ARC, in ObjCWeak Objective-C object pointers qualified with a weak lifetime are not POD or trivial types. Update the type trait code to reflect this. Copy and adapt the arc-type-traits.mm test case to verify correctness.
