4979088506 Avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB.

59b8f2e108 Fix the ORDER BY optimization logic so that it will do a block-sort on

pushUntoSorter() which is also fixed.

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]
