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.

a subtype.

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.

The first problem was reported by
[forum:/forumpost/c243b8f856|forum post c243b8f856]. That report prompted
an enhancement to the generate_series() (also included in this merge) which
in turn identified other similar issues.

on virtual tables in a compound SELECT.

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.

make sure that the selected affinity is compatible with a literal values in
arms to the left of the arm that is used to determine affinity.

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.

the subquery as correlated sot hat it is recomputed for each result and not
just computed once and reused. See
