Add support for not-null constraints on virtual generated columns
This was left out of the original patch for virtual generated columns
(commit 83ea6c54025).
This just involves a bit of extra work in the executor to expand the
generation expressions and run a "IS NOT NULL" test against them.
There is also a bit of work to make sure that not-null constraints are
checked during a table rewrite.
