Simplify ArrayToPointer conversion. Actually the only thing we need to do is to get the first element region. It is not necessary to care about the kind of the base array region.

for StringLiteral lvalue evaluation, instead of directly returning a
loc::StringLiteralVal by the Environment.

- 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)
