59145813d2 Renumber the Select.selId values in the copies of SELECT statements that 
implement VIEWs when the VIEW is expanded, so that when the same VIEW is
used twice in the same join, each expansion as a distinct selId.
This fixes ticket [ce823231949d3abf42453c8].

3e4f6c43b8 A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the 
logic a little easier to follow.  Also disallows the use of the double-quoted
string hack in the query expression used for VACUUM INTO, which is not
strictly required, but moves us toward the goal of disallowing the double-quoted
string hack everywhere.

df82afc04e Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 
string, even if the input strings are ill-formed.  This is a followup to
check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed.
Also add assert()s to prove correct zero termination.
