SUMMARY Flakey tests get two chances to pass Also, switched a bunch of tests to use new decorator. TEST PLAN Add one of these decorators to a test Edit a test to pass on the first invocation, confirm test appears as pass Edit a test to pass on the first invocation, pass on the second, confirm test appears as xfail Edit a test to fail on two consecutive runs, confirm test appears in results as fail/error Differential Revision: http://reviews.llvm.org/D10721 llvm-svn: 240789
