The tagging code was iterating over bits set in the ID_RECALC_ALL and
was casting the flag to IDRecalcFlag. This was triggering an undefined
behavior warning in Clang since the bit might not have a corresponding
value in the enumerator.

The solution is to pre-define all reacalc flags for all bits. While
this seems a bit annoying this seems to be the least fragile solution
from all suggested ones.
