[XLA] Ergonomic improvements to --xla_hlo_profile.

- Don't display ops with 0 optimal seconds and 0 actual cycles.  These
  are ops that were expected to be free and were actually free.

- Fix HloCostAnalysis to mark parameters, constants, and
  get-tuple-element as expected-to-be-free per the definition above.

- Allow optimal-seconds < 0 to indicate "I don't know".  Use this for
  custom calls, and then hide such ops from the "seconds above the
  optimum" table.

- Don't display "<none>" and "<unknown>" -- instead, just display the
  empty string.  Less visual noise.

- Instead of showing ~5 ops per category in the categories tables, show
  everything.  This isn't so noisy now that we're hiding "free" ops, and

Checkpointable: Have RNN wrappers add their cells as dependencies

Also marks _SlimRNNCell as not checkpointable, and adds a more convenient way to tag such classes.

Ideally adding a wrapper around a cell wouldn't break a checkpoint. This could look like RNN cell wrappers inheriting the dependencies of the cell they're wrapping. Possible to add that later if there's demand, or users can just add a dependency on wrapper._cell in addition to/instead of the wrapper when modifying programs.
