V8 test suites return tests by loading them into memory up-front. Up-front loading has memory and loading-time overhead for the testrunner. This CL converts the test-suites to load tests during the test run in parallel. After CL, most test suites start running immediately and all test suites start running after 3 seconds on a modern SSD. This CL eliminates the 200 MiB memory spikes that causes memory problems in mac minis.
