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.

misra.py: Treat enum constants as constant known at compile time ( #2823 )
...
C89 standard defines enum members as enumeration contants at ch.
6.4.4.3, and they are always known at compile time.
This commit fix false positives for rule 18.8 (and possible other rules
that check "constentess") with enumeration members.
