  Log Message:
  -----------
  Reapply [IR] Mark and constant expressions as undesirable

Reapply after fixing an issue in canonicalizeLogicFirst() exposed
by this change (218f97578b26f7a89f7f8ed0748c31ef0181f80a).

-----

In preparation for removing support for and expressions, mark them
as undesirable. As such, we will no longer implicitly create such
expressions, but they still exist.
