A common pattern in classes with multiple initializers is to put the
subclass's common initialization bits into a static function that receives
the value of 'self', e.g:

   if (!(self = [super init]))
     return nil;
   if (!(self = _commonInit(self)))
     return nil;

It was reported that 'self' was not set to the result of [super init].
Until we can use inter-procedural analysis, in such a call, transfer the
ObjCSelfInitChecker flags associated with 'self' to the result of the call.

We translate property accesses to obj-c messages by simulating "loads" or "stores" to properties
using a pseudo-location SVal kind (ObjCPropRef).

Checkers can now reason about obj-c messages for both explicit message expressions and implicit
messages due to property accesses.

[analyzer] Introduce ExprEngine::VisitObjCMessage for handling general ObjCMessages (both message expressions and property access)
and use it in ExprEngine::VisitObjCMessageExpr.

[analyzer] Introduce ObjCMessage which represents both explicit ObjC message expressions and implicit
messages that are sent for handling properties in dot syntax.

Replace all direct uses of ObjCMessageExpr in the checkers and checker interface with ObjCMessage.

[analyzer] Introduce ObjCSelfInitChecker, which checks initialization methods to verify that they assign 'self' to the
