Force GC between PageLoad tests. https://bugs.webkit.org/show_bug.cgi?id=98203 Reviewed by Ryosuke Niwa. Previously, our PageLoad PerfTests had multi-modal distributions, typically with a small cluster at 1-2x the median. This turned out to be caused by not garbage collecting between tests! This patch adds a new file, force-gc.html, and loads this file between PageLoad tests to force a GC. I manually verified that this cleans up our perf test outliers. PerformanceTests: * resources/force-gc.html: Added. Tools: * Scripts/webkitpy/performance_tests/perftest.py: (PageLoadingPerfTest.__init__): (PageLoadingPerfTest): (PageLoadingPerfTest.run_single): This function now loads two pages: one to force a gc and then the test to run. * Scripts/webkitpy/performance_tests/perftest_unittest.py: Modified several existing tests to show that the force-gc file is loaded.
