smartset: use native set operations as fast paths

For set operations like "&" and "-", where we know both basesets have their
sets ready, and the first set is sorted, use the native Python set
operations as a fast path.

Note: "+" is not optimized as that will break the ordering.

This leads to noticeable improvements on performance:

  revset                                | before | after | delta
  ----------------------------------------------------------------
  draft() & draft() & draft() & draft() |    776 |   477 | -39%
  draft() + draft() + draft() + draft() |   2849 |  2864 |
  draft() - draft() + draft() - draft() |    943 |   240 | -75%
  draft() - draft() - draft() - draft() |    557 |   197 | -64%
