1d4b16405b Fix a problem causing the sqlite_master entry corresponding to a virtual table
to be removed by a DROP TABLE even if the call to the vtabs xDestroy() method
failed.

bd462bcc10 Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows
a separate "INDEX" subtree for each index.  SCALAR SUBQUERY entries provide
a subquery number that is related back to the .selecttrace output.

707821ff72 Enhance the sqlite3_normalize_sql() interface so that it works even if the
prepared statement was not initially compiled using
SQLITE_PREPARE_NORMALIZED.  Enhance the ".trace" command in the CLI so that
it is able to access the full scope of functionality provided by 
sqlite3_trace_v2() and in particular so that it is able to show normalized
SQL output using the newly enhanced sqlite3_normalize_sql() interface.

[0a514e62ad1ebe5c12da8dae] did not completely address the

the register was the last instruction in the sequence for the expression, which
is not necessarily the case for expressions like CASE...END.  This revision
prevents the registered that will be recomputed from being cached in the first
place.
