[analyzer] Fix leak false positives on stuff put in C++/ObjC initializer lists.
The analyzer now realizes that C++ std::initializer_list objects and
Objective-C boxed structure/array/dictionary expressions can potentially
maintain a reference to the objects that were put into them. This avoids
false memory leak posivites and a few other issues.
This is a conservative behavior; for now, we do not model what actually happens
to the objects after being passed into such initializer lists.
