Should this refer to 754-2019 now?

Well, I just copied the current wording from llvm.minimum. I guess we should use 754-2019 now; it looks like this was discussed in D67507 but the patch wasn't applied for some reasons ...

Adding this file has made new intrinsics so much easier. I'm almost irritated at how easy this was.

LGTM We can take the IEEE 754-2019 up as a separate issue.
