- Correctly plugged Enum's GetHashCode()

- Removed GetHashCode() methods that were not really needed - Plugged class CultureInfo for GetHashCode() - Plugged class Runtime.CompilerServices for GetHashCode() - Plugged class RuntimeTypeImpl for GetHashCode() - Fixed tests that were failing using true .NET GetHashCode() - Fixed IL Interpreter added SHIFT, AND, XOR... for sbyte and short
