Increase test runner speed.

Increase test runner speed.

Let the test runner preserve the order of test suites to let suites with long running tests run first.

Mark some tests as slow that can now be skipped via --slow-tests=skip.

SLOW]],
Threading* tests are a summary of essentially normal tests that are defined
using the THREADED_TEST macro instead of TEST. So we already have
single-threaded coverage on those tests, but run them multi-threaded again. In
order to reduce runtime, Threading tests are divided into four parts. It just
happens that parts 2 and 3 are somewhat faster, but it seems arbitrary to me to
mark only 1 and 4 as slow.

Imo we can remove all 4 parts.

Or divide them into more parts, but that probably wouldn't make the total run
time any faster.
