mechanism is changed to take affinity and collation into account. This
seems to give correct answers. But the search for constant propagation
costs 4 million cycles in the speed test.

WHERE close, not just those that contain a subquery. This then demonstrates
that the current implementation is inadequate since it does not take into
account collating sequences.

macros said a branch could not be taken when in fact it could be. Alter
some window function branch coverage macros to indicate that comparison
operands cannot be NULL.

testing logic. Provide new macros that allow the code to specify that
some branch instructions can never take the NULL path and that the OP_Jump
opcode is only interested in equal/not-equal. The
SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly
differently (it provides the callback with a bitmask of the branch action,
rather than an integer).
