Recycle memory for GRStates that are never referenced

by ExplodedNodes. This leads to about a 4-8%
reduction in memory footprint when analyzing

[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.

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.

Implement support for pack expansions whose pattern is a non-type
...
template argument (described by an expression, of course). For
example:
template<int...> struct int_tuple { };
template<int ...Values>
struct square {
typedef int_tuple<(Values*Values)...> type;
};
It also lays the foundation for pack expansions in an initializer-list.
