Produce SymbolCast for integral types in `evalCast` function. Apply several simplification techniques while producing the symbols. Added a boolean option `handle-integral-cast-for-ranges` under `-analyzer-config` flag. Disabled the feature by default. Replace `SValBuilder::evalIntegralCast` with `SValBuilder::evalCast`. Remove `SValBuilder::evalIntegralCast` as unnecessary one.
