[PATCH] D31005: [Objective-C] Fix "repeated use of weak" warning with -fobjc-weak

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

bkelley created this revision.

-Warc-repeated-use-of-weak should produce the same warnings with -fobjc-weak as it does with -objc-arc. Also check for ObjCWeak along with ObjCAutoRefCount when recording the use of an evaluated weak variable. Add a -fobjc-weak run to the existing arc-repeated-weak test case and adapt it slightly to work in both modes.
