ae80ddea9f Remove the Expr.pColl field and compute the collating sequence as it is needed. 
This fixes the test script "shared9.test", though there is still a memory leak.
And there are other problems.  Consider this a work-in-progress.

a9e3fc05f5 Fix some corner case behavior in the new ORDER BY optimization logic. 
Remove the SQLITE_OrderByIdx bit from the 
SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many
TH3 tests to fail when the NO_OPT configuration parameter was engaged,
and since there really isn't any need to turn that optimization off.
The SQLITE_OrderByIdxJoin bit remains.

index in general and for joins.  Use macros to test for bits in the 
disabled-optimization bit vector, in order to make the code clearer.

428c218c90 When reusing pages as part of creating a new index, allocate the leaves from each free-list trunk page in ascending order, instead of trying to maximize localization for each individual allocation. This increases the chance that pages will be written to disk in ascending order by a large CREATE INDEX statement, improving overall performance.
