Zhongxing Xu 83aff7079f Process decls in RegionStore. Individual elements of fixed size arrays are

Ted Kremenek 8b103c65c6 - constify some uses of MemRegion* (MemRegion should be immutable). 
- Added new region "SymbolicRegion", which maps symbol values to the region domain.
- Enhanced BasicStore::getFieldLValue() to return a FieldRegion (using SymbolicRegion)
- Added some utility methods to GRState for fetch svals from the store.
- Fixed regression in CheckNSError (we weren't getting the value bound to the parameter)

Zhongxing Xu d9959aee34 This is the first step to implement a field-sensitive store model. Other things are simplified: no heap shape assumption, no parameter alias assumption, etc.
