[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.

RegionStore can't actually reason about this,
so we were getting bogus warnings about loading
uninitialized values from the array.  The solution
is invalidate the entire array when we cannot
represent the binding explicitly.

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

It also lays the foundation for pack expansions in an initializer-list.
