5d783d5c84 Fix aggregate function processing to correctly deal with OOMs inside of 
sqlite3ParserAddCleanup(). 
(dbsqlfuzz b2d11ca70e55ee8bde48ae0b53fa3e9355812f95).
Also add improved testing support by causing sqlite3FaultSim(300) to
simulate an OOM inside of sqlite3ParserAddCleanup() and by adding
improved fault-sim support to the CLI.

[forum:/forumpost/4cf69794d9dfff7c|forum thread 4cf69794d9dfff7c] in two
different ways:  (1) Omit the call to PRAGMA integrity_check('X') that was
being done after CREATE TABLE "X" because the result was being ignored and
the integrity_check was not doing anything other than burning CPU cycles.
(2) Do not interpret the argument to PRAGMA integrity_check as a number if it
is in fact a string that looks like a number.

ec14ef80b0 Improvement to the way that affinity is determined for columns of a 
compound subquery.  The affinity is the affinity of the left-most
arm of the compound subquery that has an affinity other than NONE, adjusted
to accommodate the data types coming out of the other arms.

23afc2c4ec Back out the previous change on this branch. In its place: Determine the 
affinity of a subquery by the left-most arm of the subquery that has an
affinity other than NONE.  In other words, scan from left to right looking
for an arm of the compound subquery with an affinity of BLOB, TEXT, INTEGER,
or REAL and pick the first one found.  Or stay with NONE if no arm has a
defined affinity.  Test cases added.

2469350ad9 For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db.
