  test: Replace _TEST_CASE_ with _TEST_SUITE_.
  
  Googletest is (at last) converging with industry-standard terminology
  [1]. We previously called test suites "test cases", which was rather
  confusing for folks coming from any other testing framework.
  
  Chrome now has a googletest version that supports _TEST_SUITE_ macros
  instead of _TEST_CASE_, so this CL cleans up some of the outdated usage.
