[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.

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,

is invalidate the entire array when we cannot
represent the binding explicitly.
