Log Message:
make: replace VarExprFlags with VarExprStatus

The combination of !VEF_UNDEF && VEF_DEF was not possible, which made it
rather strange to model this state as a bit set.

The only functional change is the renamed constants in the debug output.

Using ENUM_VALUE_RTTI_2 felt like overengineering since it's harder to
understand than a simple array of names.
