ishell a8a432701f [tests] Cleanup tests that use assertOptimized()/assertUnoptimized().
This CL adds --crankshaft and --no-always-opt flags to the tests that use
assertOptimized() and assertUnoptimized() respectively.

This CL also adds presubmit checks that ensure that tests have the proper
flags set.
