conceptually, the issue is that there are multiple sets of built-ins

I don't understand this. We're committed to one runtime per
compilation, right? If so, then we should create only one of the sets
at any time.
Yes, that's true [notwithstanding an erroneous invocation of LTO with
mixed inputs, which we should detect by alternate means]
but ...
.. don't the indices for built-ins need to be constant?
(maybe that means that we'd just allocate as many as needed to
cover all runtimes?)
.. or, otherwise, how does LTO know which set to invoke?
... sorry, I think my observation about pr24777 has pushed this thread
off course - perhaps we'd be better putting this in the PR thread?
