the body of the search.

4a1d365903 Add OP_IdxGT and OP_IdxLE as distinct opcodes. Formerly these operations where
done using OP_IdxGE and OP_IdxLT with the P5 flag set.  But VDBE code is easier
to read with distinct opcode names.  Also change OP_SeekGe to OP_SeekGE, and
so forth, so that the capitalization is consistent.  The whole point of this
change is to improve the readability of VDBE listings.

e0670b6220 Remove the "rowid cache" that sought to remember the largest rowid for a
table and thereby speed up OP_NewRowid.  That cache was ineffective.
Removing it results in a performance increase of 0.4%, less memory usage,
and a slightly smaller library size.
