[LLVMdev] Removing legacy profiling code from LLVM

[msharp at codeaurora.org]

It appears to me as if you're proposing removing all the existing
readers/writers, both the really old ones and the metadata ones, the
instrumentation passes, and the implied file format for profile data.  Is
this correct?

While I'm not against considering migrating our work, I think it would be
better if the new system was in place before removing the old.
