As I explained in the original PR, I think this is a fairly important fix since that was an unintentional change in LLVM 19, but this can also potentially break people who compiled with LLVM 19.1. Since we're making the fix on `main`, it will land in LLVM 20 anyway and I think it's best to land sooner rather than later, but I'll let the release manager decide.

@tru If you need additional context or information about this change, feel free to ping me on Discord and we could even set up a quick chat.
