Hans Boehm 3f5578708d Add "benchmark" to time atomic operations
The intent here is to confirm that the compiler behaves as expected,
and to guide optimization efforts, particularly where there is a
choice between primitives.

Test: Built and ran benchmark on Angler repeatedly. Manually confirmed
that the compiler behaves roughly as expected.
