1550771a6a Fix a case where an error in the ORDER BY clause of an aggregate function that is part of a trigger body might cause an assert() to fail in an ALTER TABLE command.

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.

325420616f The sqlite3FaultSim(300) error from [1e8863909ac369e5] must be treated as 
an OOM, since it simulates an OOM.  Also fix deferred deletion of Expr objects
from [a53bdd311c4154fd] so that it does not corrupt the AST if an OOM occurs.

d059774365 Fix the CREATE TABLE performance issue described by 
[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.
