[Frontend] -validate-tbd-against-ir has 3 levels of validation.

Browse Source 
It can now:

- not validate (=none)
- validate that all symbols in the IR are also in the TBD (=missing),
- validate the above, and also that all in the TBD are in the IR (=all).

The first and last were switched between with the old boolean flag, the
second is new.
