Emilio G. Cota 070e3edcea tests: add atomic_add-bench 
With this microbenchmark we can measure the overhead of emulating atomic
instructions with a configurable degree of contention.

The benchmark spawns $n threads, each performing $o atomic ops (additions)
in a loop. Each atomic operation is performed on a different cache line
(assuming lines are 64b long) that is randomly selected from a range [0, $r).

[ Note: each $foo corresponds to a -foo flag ]
