 // Is this derived type TEAM_TYPE from module ISO_FORTRAN_ENV?

I don't have a strong feeling where they should go, but if I move the new functions, then I think those other functions should probably also be moved. What do you think?
> Gee, `IsTeamType` is referenced in `Evaluate/intrinsics.cpp`, so it can't be moved even though it's logically related to the other functions.  But `IsEventTypeOrLockType` is only referenced from the `Semantics` directory.  For locality of reference, it make sense to me to move them.
What you said about `IsTeamType` reminded me, I will need to call `IsEventType` from `Evaluate/intrinsics.cpp` as well when I add `event_query` to the list of intrinsic subroutines. I will not need to call `IsLockType` from that file. What would you think in that case? Still move `IsEventType`, `IsLockType`, and `IsEventTypeOrLockType`? Or just the last two that don't/won't have references in the `Evaluate` directory?

@klausler It looks like you originally wrote `IsEventTypeOrLockType` and `IsTeamType`, do you have an opinion on this?
