After further discussion, remove all the default assignment operators.

jmlait · jmlait · commit df2d3d8cca40 · 2023-01-25T12:14:13.000-05:00
If you specify an assignment operator (even if default) you should
also be specifying a copy constructor.  We haven't done the latter, so
should just leave as rule-of-zero.
