4a642b6060 Improvements to the way that OOM errors are processed.

1b32554b80 Enhance the internal sqlite3VdbeAddOpList() interface to automatically update
jump destinations.  Use this feature to simplify the AUTOINCREMENT code
generator.

b89aeb6aa2 Add assert() statements on the nExtraDelete variable in vdbe.c to try to verify
that the FORDELETE and IDXDELETE flags are being generated correctly.  Those
flags are not currently generated correctly, and so the assert()s trip on this
check-in.
