Basically NFC: A TEST/TEST_F/etc that bails out early (usually because setup failed or some other runtime condition wasn't met) generally should use GTEST_SKIP() to report its status correctly, unless it takes steps to report another status (e.g., FAIL()). I did see a handful of tests show up as SKIPPED after this change, which is not unexpected. The status seemed appropriate in all the new cases.
