detect if a cell still needs interpreting after Interpret()

https://bugs.documentfoundation.org/attachment.cgi?id=51878
after hard-recalc asserts because of not having cell dependencies
non-dirty for threaded calculation. This is because Interpret()
actually sometimes returns without computing a value for the cell,
e.g. when it backs out because of a need to do iteration.
This is handled when Interpret() is called from InterpretTail(),
but ScDependantsCalculator does not handle this and considers
all cells interpreted, unless it detected a problem.
We've already fixed a number of such bugs, and given that there
are still problematic corner cases after all this time, add code
simply detecting this generic problem and avoiding threading
in that case, with a SAL_WARN. This does not fix the problem
itself, but at least now it's handled.
