Anna Zaks 228f9c7b68 [analyzer] Allow pointers escape through calls containing callback args. 
(Since we don't have a generic pointer escape callback, modify
ExprEngineCallAndReturn as well as the malloc checker.)

Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared. 
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Ted Kremenek 3bc5372fae [analyzer] teach analyzer about ObjC literals, thus trimming out a false positive with the malloc() checker involving 
comparing literal addresses to nil.

Fixes <rdar://problem/10579586>
