  [SCCP] Avoid some uses of SCCPSolver::isOverdefined (NFCI)

This is a confusingly named helper than means "is not unknown,
undef or constant". Prefer the more obvious ValueLattice API
instead. Most of these checks are for values which are forced to
overdefined by undef resolution, in which case only actual
overdefined values are relevant.
