Add whole-program vtable optimization feature to Clang. This patch introduces the -fwhole-program-vtables flag, which enables the whole-program vtable optimization feature (D16795) in Clang. Differential Revision: http://reviews.llvm.org/D16821 llvm-svn: 261767

Use -- to prevent the driver from confusing paths with flags, should fix Mac bot. llvm-svn: 313201

// NO-LTO: invalid argument '-fwhole-program-vtables' only allowed with '-flto'
Driver: Make -fwhole-program-vtables a core option so it can be used from clang-cl. Also add some missing driver tests for the regular clang driver. Differential Revision: https://reviews.llvm.org/D37787 llvm-svn: 313169
