e6f85e71e9 Fix ticket #1046 by removing code and simplifying the query optimizer.

9012bcbc0a The optimizer now uses only the index and ignores the table if it can get
away with doing so, thus saving a single BTree search per row of result.
This could potentially double the speed of certain queries.  The
code passes all regression tests but new tests to exercise the new
functionality are yet to be added. (CVS 2170)
