This adds adds four macros when compiling using GTEST_OS_MAC:
{ASSERT,EXPECT}_NS{NE,EQ}. These test ObjC objects using |-isEqual:| and prints failures using the |-description| selector. This allows for better debugging output with ObjC++ test cases. BUG=http://code.google.com/p/googletest/issues/detail?id=303 TEST=Covered by unit tests. Review URL: http://codereview.chromium.org/3028047 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@55180 0039d316-1c4b-4281-b951-d872f2087c98
