drh 6a03a1c5f7 For infix functions (LIKE, GLOB, REGEXP, and MATCH) treat the left 
operand as the first argument for the purposes of virtual table
function overloading, even though the left operand is really the
the second argument. (CVS 3324)

# Organization of tests in this file:
#
# vtab1-1.*: Error conditions and other issues surrounding creation/connection
# of a virtual module.
# vtab1-2.*: Test sqlite3_declare_vtab() and the xConnect/xDisconnect methods.
# vtab1-3.*: Table scans and WHERE clauses.
# vtab1-4.*: Table scans and ORDER BY clauses.
# vtab1-5.*: Test queries that include joins. This brings the
# sqlite3_index_info.estimatedCost variable into play.
# vtab1-6.*: Test UPDATE/INSERT/DELETE on vtables.
# vtab1-7.*: Test sqlite3_last_insert_rowid().
#
# This file uses the "echo" module (see src/test8.c). Refer to comments
# in that file for the special behaviour of the Tcl $echo_module variable.
