comparison if the index uses the built-in BINARY collation.
Indexes in the schema already got this fast path because they record BINARY
as a NULL collation pointer.

b5e3cf0655 The testrunner.tcl script is enhanced so that --stop-on-error does not 
exit immediately, but instead  marks all pending tasks as "halt" so
that no new tasks are scheduled, but allows "running" tasks to continue
on to completion, as an immediate halt can cause hung processes on  Windows.
Also, in Makefile.msc, the "test" target now includes --stop-on-error.
