f5601cac4d Fix a potential buffer overread in sqlite3VdbeRecordCompare() when a 
serial_type specifies a field that starts in bounds but is much too large
for the allocated buffer.  Mostly harmless.  The overread is unlikely to
go more than one or two bytes past the end of the buffer.

828463375c An improved method for avoiding the use of the STAT3 samples to compute 
the estimated number of outputs when the left-most index is equality
constrained.  This check-in undoes the previous fix and applies a new one.

4bd5f73fa0 Add logic to the query planner to only use partial indices if the WHERE clause 
constrains the search to rows covered by the partial index.  This is just
infrastructure.  The key routine, sqlite3ExprImpliesExpr(), is currently a
no-op so that partial indices will never be used.
