5b1420e046 Remove a testcase() that is now always true due to the "x IN (?)" optimization. 
Add an ALWAYS() around a conditional in the parser that cannot be false.

fbb24d1092 The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is 
incorrect, as demonstrated by the in4-5.1 test case in this check-in.
The "COLLATE binary" that was being added to the RHS of IN was overriding
the implicit collating sequence of the LHS.  This change defines the EP_Generic
expression node property that blocks all affinity or collating sequence
information in the expression subtree and adds that property to the expression
taken from RHS of the IN operator.

0a8d14261c Previous check-in is not quite correct. "x IN (?)" is not exactly the same 
as "x==?" do to collation and affinity issues.  The correct converstion should
be to "x==(+? COLLATE binary)".  The current check-in fixes this problem and
provides test cases.  Ticket [e39d032577df69]

e0670b6220 Remove the "rowid cache" that sought to remember the largest rowid for a 
table and thereby speed up OP_NewRowid.  That cache was ineffective.
Removing it results in a performance increase of 0.4%, less memory usage,
and a slightly smaller library size.
