Must use sqlite3IntFloatCompare() for accurate comparisons between very large integer and floating point values in RTREE. Otherwise the comparison does not work on all platforms. Further fix to [027e5336acc26f57]. (check-in: 820f106a user: drh tags: trunk)

Remove code that added a P4 parameter to the OP_Variable opcode. This is no longer required. (check-in: dd5977c9 user: dan tags: trunk)
