This makes test outcomes immutable. This has two benefits: 1) It's more robust. Using the |= operator by mistake wouldn't lead to unwanted mutation. 2) It's faster as now the set reference can be copied again when copying test cases. Test case copying happens an order of magnitude more often than rules do apply. BUG=v8:5238 Review-Url: https://codereview.chromium.org/2212333002 Cr-Commit-Position: refs/heads/master@{#38373}
