47ce12d239 Fix the tclsqlite.c TCL interface module so that it works with both Tcl8 and 
Tcl9.  Make changes across the TCL-based test harness to enable SQLite to
be tested with either Tcl8 or Tcl9.  Get the --with-tcl= argument on the
configure script working.  Testing changes only - no changes to the SQLite core.

e8ba446a9a Assume that an SQL function is able to return a subtype if any of its 
arguments are SQL functions that are able to return subtypes.  This closes
a corner-case hole in the patch at [ba789a7804ab96d8].

2eb9adb564 Assume that a function is able to return a subtype if either (1) it is itself 
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.

0901571f0a The coalesce(), ifnull(), and iif() functions pass through subtype values 
from their arguments, and hence need to have the SQLITE_RESULT_SUBTYPE flag
set.  This fixes an corner-case for the patch at [ba789a7804ab96d8].

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.
