Ted Kremenek bd862711fd Fix PR 7475 by enhancing the static analyzer to also invalidate bindings for non-static global variables 
when calling a function/method whose impact on global variables we cannot accurately estimate.
This change introduces two new MemSpaceRegions that divide up the memory space of globals, and causes
RegionStore and BasicStore to consult a binding to the NonStaticGlobalsMemSpaceRegion when lazily
determining the value of a global.

Zhongxing Xu d4f1294f1e Remove extents of dead symbolic regions when RemoveDeadBindings. 
This requires creating new persistent states due to the nature of GDM.

their bindings are not removed.

Zhongxing Xu 6d3cc382df Since now we store the cast type with an ElementRegion, there is 
no need to store a type with SymbolRegionValue.

Zhongxing Xu b02d4a0d11 Unify the implementation of getLValueElement of store managers. 
It's more sophisticated than the original one of BasicStore. But it does
matter.
