This reverts commit 24e521c6.

Reason for revert: bug has been found and fixed

Original change's description:
> Track progress through View destructor
>
> The View destructor ends up in an impossible state which means that
> execution must have branched to the middle of it, but it is not clear
> how this could happen. This change adds an array of line numbers that is
> filled in as the destructor runs to leave us some bread crumbs. It also
> records the vtable of the about-to-be-deleted child object so that we
> can investigate if this is a type-related bug.
