8c8a8c4573 More than double the speed of the resolveP2Values() routine in vdbeaux.c by 
moving from an extended if-else on every opcode to a switch.  Opcodes are
reordered in mkopcodesh.awk to put the switched opcodes close together,
for additional performance and to reduce code footprint.

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.

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.
