Thanks for your suggestion, I tried it. This is the patch: https://github.com/pcc/llvm-project/tree/pfp-autxmxn

I found that it was more code (it adds 102 insertions(+), 66 deletions(-) on top of this patch). And I only implemented the SDAG side so far, not GISel. So I'm inclined not to go with it and instead try to improve the naming of the X16X17Safer stuff in this patch.
