PR13684: Emit vtable entries for deleted functions as __cxa_deleted_function. This is consistent/interoperable with GCC 4.7 (& __cxa_deleted_function isn't present in 4.4 - not sure when it got added, but you'll need something with that function available for this to work). llvm-svn: 166069

Emit DeferredDeclsToEmit in a DFS order. Currently we emit DeferredDeclsToEmit in reverse order. This patch changes that. The advantages of the change are that * The output order is a bit closer to the source order. The change to test/CodeGenCXX/pod-member-memcpys.cpp is a good example. * If we decide to deffer more, it will not cause as large changes in the estcases as it would without this patch. llvm-svn: 226751
