Where are we on getting these patches pushed? I think the reason that
BF member midge has been failing of late is that it's running LLVM 22
(if not indeed something even newer --- configure doesn't report
the clang version, sadly). Also, I've reproduced this symptom:

Intrinsic has incorrect argument type!
ptr @llvm.lifetime.end.p0

ptr @llvm.lifetime.end.p0
2026-03-31 18:58:20.218 EDT [28486] FATAL: fatal llvm error: Broken module found, compilation aborted!

on a fresh Fedora 44/x86_64 installation with llvm 22.1.1. So this is
going to be a production compiler RSN. (F44 is still labeled beta,
but not for much longer.)
