Avoid clarifyCalculation warning for 'x % 16 ? 1 : 0' expression. Fixes FP seen in daca@home. It seems likely that the order is understood otherwise the ternary calculation could easily be simplified away.

fix daca insighttoolkit crash in template simplifier ( #2826 )
...
Don't count deleted instantiations in the recursive count.
I can't reduce the daca code because creduce requires a preprocessed
file to reduce and the problem doesn't show up when the file is
preprocessed with cppcheck.
There is no test because I couldn't reduce the problem files.
