Find the region from which this symbol originates.

Whenever the symbol was constructed to denote an unknown value of a certain memory region, return this region. This method allows checkers to make decisions depending on the origin of the symbol. Symbol classes for which the origin region is known include SymbolRegionValue which denotes the value of the region before the beginning of the analysis, and SymbolDerived which denotes the value of a certain memory region after its super region (a memory space or a larger record region) is default-bound with a certain symbol.

Reimplemented in clang::ento::SymbolDerived, and clang::ento::SymbolRegionValue.
