vleschuk added a comment.

- Switched to ADT/BitmaskEnum for DIFlags
- Added "special" flags: FlagLargest and FlagZero (FlagLargest can be disabled in DebugInfoFlags.def to avoid problems with duplicate cases in switch statements)
- For types derived from DINode added several overloaded methods which take either underlying enum type or enum itself. This was done to avoid lots of static_casts in other modules.
- Edited tests to use DIFlags
