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. BUG=v8:5890 Review-Url: https://codereview.chromium.org/2653753007 Cr-Commit-Position: refs/heads/master@{#42709}
