[LLVMdev] Help adding the Bullet physics sdk benchmark to the LLVM test suite?

This is pretty interesting approach. However, for now I'm more
concerned about code speed, I'm seeing that llvm-generated code is
slower that gcc-generated one on at least two platforms (20% on x86-64
& even more on arm), so, I suspect an optimization deficiency is
somewhere...
