Make MaybeInterpret, NeedsInterpret, IsDirtyOrInTableOpDirty inline

because they are in the hot path of the most common workload.
For example, in SUM(A1:A50000) where column A is itself a
formula-group, in threaded mode(default) A1:A50000 will already
be evaluated, so cost to calling MaybeInterpret/NeedsInterpret etc
should be as minimal as possible.
