fixes https://github.com/llvm/llvm-project/issues/73588 The aarch64 version of `frintn.ll` notes the intention to auto-upgrade `frintn` to `roundeven`. I haven't been able to figure out how to make that happen though (either for arm or aarch64). The original issue came up in https://github.com/rust-lang/stdarch/pull/1807
