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

[John McCall via Phabricator via cfe-commits]

I have similar feedback here to the other patch.  Please try to see if there's some reasonable way to make this dependent just on the lifetime qualifier without paying attention to the language options.  If we, say, decide to start supporting __strong in non-ARC modes, it'd be nice if that just worked without having to revisit all of this code.
