Split -Wdelete-non-virtual-dtor into -Wdelete-abstract-non-virtual-dtor
-Wdelete-non-virtual-dtor previously controlled two diagnostics: 1)
calling a non-virtual dtor from an abstract class, and 2) calling a
non-virtual dtor from a polymorphic class. 1) is a lot more severe
than 2), since 1) is a guaranteed crash, but 2) is just "code smell".
Previously, projects compiled with -Wall -Wno-delete-non-virtual-dtor,
which is somewhat reasonable, silently crashed on 1).
