<pre>Originally, I'd planned to move `GenericDebugNode` in underneath the
`DIDescriptor` classes as part of PR22235. This would have required updating
all the testcases to use it, only to subsequently update every line *again* as
I implemented the more specialized nodes (making schema changes along the way).
Instead I'll be proceeding as follows: add specialized nodes that match the
current schema, add assembly/bitcode support for them, move them all underneath
the `DIDescriptor` hierarchy (only requiring each line to be updated *once*),
and then start hacking the schema once they're in place.
This PR is to track the work to build the new hierarchy and move it into place.</pre>
