Rich Trott a7335bd1f0 test,benchmark: use deepStrictEqual()
In preparation for a lint rule that will enforce
assert.deepStrictEqual() over assert.deepEqual(), change tests and
benchmarks accordingly. For tests and benchmarks that are testing or
benchmarking assert.deepEqual() itself, apply a comment to ignore the
upcoming rule.
