There are no plans to integrate LLVM with mainline GCC.  LLVM  
maintains its own permanent fork of GCC, which we periodically sync  
up with GCC's progress (e.g. LLVM 2.2 will include a GCC 4.2 based  
front-end).  There is also work underway to build llvm-native front- 
end technology (http://clang.llvm.org).

If you want LTO today, feel free to go to http://llvm.org/ :)  
otherwise LLVM is irrelevant to this discussion.
