I added bullet to LLVM testsuite. Basically I had to flatten source
directories since this is a current requirement of the llvm testsuite
harness.
Some include paths tweaks were required due to this. Also, I disabled
the time reports, since otherwise we cannot compare the outputs.

bullet appeared to be ~20% slower for me compared to gcc 4.2.4, so,
definitely something should be worked on :)

One questions though: is it possible to "verify" the results of all
the computations somehow? We need to care not only about speed, but
about correctness too :)
