ClearCase: change QTC_CHECK to QTC_ASSERT and remove dead stores.
ClearCase: change QTC_CHECK to QTC_ASSERT and remove dead stores.

When the QTC_CHECK would fail, a nullptr deref would happen directly
after the check.

The dead stores are not harmfull, but add noise when checking for dead
stores that are due to logic errors.
