as used. The problem only happens with constexpr variable, for constexpr variable, variable is not marked during parser variable. This is because compiler might find some var's associate expressions may not actully an odr-used later, the variables get kept in MaybeODRUseExprs, in normal case, at end of process fullExpr, the variable will be marked during the call to CleanupVarDeclMarking(). Since we are processing expression of OpenMP clauses, and the ActOnFinishFullExpr is not getting called that casue variable is not get marked. One way to fix this is to call CleanupVarDeclMarking() in EndOpenMPClause for each omp directive.
