/cherry-pick ff31020

Looks to be necessary to build Julia with Opaque Pointers turned on (do we backport those kinds of patches yet?)

@nikic What do you think about backporting this? ff31020

[nikic]

I don't think it makes sense to backport opaque pointer changes to LLVM 14. The overall state wasn't quite good enough at the time the branch was cut.
