The only thing that needs to be unique is the struct tracepoint
__tracepoint_##name. There should not be any duplicates of those. I
can't see how the LTO would duplicate a data structure without screwing
everything (not just tracepoints) up.

We can still have more than one trace_##name() called, as that is
handled by the static key.

Note, I'm scrambling to get ready for my trip tomorrow. Thus, I'm not
as much at the computer. I may work on some patches in my 6 hour
layover though.
