  Don't inherit ANGLETest SetUp and TearDown.
  
  Instead of inheriting from testing::Test's SetUp and TearDown we add
  new methods 'testSetUp' and 'testTearDown'. This helps prevent a common
  error of forgetting to call the base class method.
  
  Also add a check in the ANGLETest destructor that SetUp and TearDown
  have been called.
