781163aa9d When the database encoding is UTF-16LE and the GLOB optimization is used, 
it is ok to use the range search over an index, but it is not ok to
disable the actual GLOB function call.

6ad4e9fd2a Fix for the UTF-16LE problem reporte by 
[forum:/forumpost/dc7e1b7527e84343|forum post dc7e1b7527e84343].  Because of
the unexpected ordering of characters using the default collation (memcmp()
order) in UTF-16LE, the LIKE/GLOB optimization restricts its attention to
the pattern prefix that is all ASCII, which is the common case.

1521ca4c20 Refactor the SrcItem object so that information about subqueries is stored 
in a separately allocated Subquery object.  This reduces the memory requirements
for SrcItem and makes the code run faster.  It also provides an expansion path
for subquery processing that does not burden simple queries.  The current
checking mostly works, but there are still issues that need to be tracked
down and fixed.
