This code is just a move of something already in llvm.  I'm currently  
bugging
the performance tools guys here for a better way to do this, and have  
hopes
of something reasonably soon I can add into llvm.  That said, as far  
as I can tell
from asking this code doesn't work with any performance tools at apple
and is off by default :)
