bcba3655ee Add support for the sqlite3_vtab_distinct() interface. Virtual table 
implementations can use this API to determine more detail about the ordering
requirements needed by the query plan and perhaps reduce the amount of
work required to compute a correct answer.  This is an optimization
opportunity for the virtual table implementation.  The correct answer should
still be obtained (though perhaps more slowly) even if sqlite3_vtab_distinct()
is ignored.

routine and into a separate "no-inline" subroutine, in order to reduce the
complexity of sqlite3WhereBegin() and thereby encourage C compilers to
inline sqlite3WhereCodeOneLoopStart().
