SI-9369 Fix pattern matcher warnings for diamond shaped inheritance.
A previous optimization (d44a86f432a7f9ca250b014acdeab02ac9f2c304) for
pattern matcher exhaustivity checks used a smarter encoding to ensure
that the scrutinee can be equal to one child only.
However, in case of traits between the root and leave type, a child can
be of several types and these types should not be in a mutually exclusive
group. A simple solution (hat tip to retronym) is to just put traits
and classes into separate groups.
