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

[Daniel Dunbar]

This is an excellent addition, thanks a lot Anton!

So far it looks like its working on ppc/x86_64 and some ARM testers.
It's not working on smoosh-01 yet (the buildbot driven nightly
tester), I will try to investigate...
