Although the original intent of this patch was to resolve an assertion issue (https://github.com/ziglang/zig-bootstrap/issues/164#issuecomment-2332357069), it actually addresses two miscompilation issues (https://github.com/llvm/llvm-project/issues/97975 https://github.com/llvm/llvm-project/issues/97981) as well. When the backport was initially proposed, I was believed that an ABI change would be necessary to ensure compatibility with future hardware supporting fp16. However, it's now clear that no such change will be required (https://github.com/llvm/llvm-project/pull/109368#issuecomment-2423879356). Given that this is primarily a bug fix, could we proceed with merging this backport into 19?
