Restore REINDEX constraint validation.

Browse Source 
Refactoring as part of commit 8ceb245680
had the unintended effect of making REINDEX TABLE and REINDEX DATABASE
no longer validate constraints enforced by the indexes in question;
REINDEX INDEX still did so.  Indexes marked invalid remained so, and
constraint violations arising from data corruption went undetected.
Back-patch to 9.0, like the causative commit.
