Title: Make atomic_test and spinlock_test run for many more iterations, and time their results.

Make atomic_test and spinlock_test run for many more iterations, and time their results.

This allows us to rigorously compare the speed of our atomics and spin locks.
Also make their output a little neater by locking around the status printouts, and
eliminate the #if's that provide safety for Boost < 1.35, which is no longer supported.
