drh f163bfba4e If the argument to REINDEX is EXPRESSIONS (with no schema prefix) then it 
updates both expression indexes, and any indexes named "expressions" or
all indexes of any tables name "expressions".

drh b425ebdd4f Add logic to silently and transparently deal with stale expression index 
values when deleting or update a table row, instead of reporting a corrupt
database.  Enhance PRAGMA integrity_check to identify non-serious
stale expression index entries as such, rather than proclaiming that the
indexes is broken.
