As part of WT-9937, we added a way to test testutil_parse_opts in test/suite/wt9937_parse_opts. The test depends on the layout of TEST_OPTS to initialize a static array of expected values. However, every time we add a field to the test utility's TEST_OPTS, there is kind of an unexpected dependency, where we need to adjust the test program. There's a better way to set up the static array to eliminate this extra dependency. SInce our project will be adding more fields to TEST_OPTS here and there and probably beyond this project, this should be fixed.
