Attached is the target independent llvm.atomic.barrier support, as well as alpha and x86 (sse2) support. This matches Chandler's definitions, and the LangRef patch will just restore that. Non-sse2 barrier will be needed, I think it is "lock; mov %esp, %esp", but I'm not sure. Any objections? I'll take a hack at the front end support for __sync_synchronize after this
