ade45d9703 Recycle memory for GRStates that are never referenced

reduction in memory footprint when analyzing

ffb08c46fa [analyzer] Handle the dot syntax for properties in the ExprEngine. 
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.

and use it in ExprEngine::VisitObjCMessageExpr.

37ab726d63 [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.

cdbc539aee Introduce a new expression kind, SubstNonTypeTemplateParmPackExpr, 
that captures the substitution of a non-type template argument pack
for a non-type template parameter pack within a pack expansion that
cannot be fully expanded. This follows the approach taken by
SubstTemplateTypeParmPackType.

95d874fa5d Teach RegionStore::EnterStackFrame() to handle 
the case where the called function has fewer
formal arguments than actual arguments.  This

0d87e0c65b Support inlining base initializers. We still haven't got it completely right, 
since the bindings are purged after they are set up. Need to investigate
RemoveDeadBindings algorithm.

304b6e4aa1 Fix a corner case in RegionStore where we assign 
a struct value to a symbolic index into array.
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.
