Re-enable format string warnings on printf. The warnings are still incomplete. Apparently it is undefined to use a vector specifier without a length modifier, which is not currently warned on. Additionally, type warnings appear to not be working with the hh modifier, and aren't warning on all of the special restrictions from c99 printf. llvm-svn: 352540
