[clang][DR] Test and mark DR1305 as complete

Browse Source 
DR: http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1305

This DR has always been implemented in all clang versions as far back as I could go. This patch basically just adds a test with the needed comments to mark it as complete.
