Hash : 9550c603
Message : Code refactoring for end2end tests. This change: 1) uses the new style ANGLE_SKIP_TEST_IF to skip tests. 2) replaces compile-time definition for OSX to skip tests by run-time function IsOSX() to skip tests, in order to align with ANGLE_SKIP_TEST_IF. 3) fixes a couple of typos.
