sqlite3_vtab_distinct() to return 2 or 3 if the rowid column of the virtual
table is used, as doing so might lead to an incorrect answer.

3 mean that all rows must be distinct over "colUsed" which is a superset of
"aOrderBy". Also, disallow return codes 2 and 3 if the rowid of the virtual
table is accessed.

are both made obsolete by the previous fix on this branch.

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.

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.

OSSFuzz while it is running the latest ASAN.

arguments are SQL functions that are able to return subtypes. This closes
a corner-case hole in the patch at [ba789a7804ab96d8].

marked with SQLITE_RESULT_SUBTYPE, or (2) one of its arguments is a function
that is able to return a subtype. This check-in backs out the code changes
from the previous two on this same branch, but keeps the test cases from
the previous two.

set. This fixes an corner-case for the patch at [ba789a7804ab96d8].

[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.

PRAGMA integrity_check as a number. Treat it as a table name that just
happens to look like a number.

because it is a no-op. Even if the integrity_check failes, the CREATE TABLE
is stull successful. The OP_SqlExec just burns CPU cycles for no reason.
