So I didn't want this to be blocked until this seemingly low-profile PR gets reviewed. The patch is very simple and the whole point was to make FreeBSD CURRENT use IEEE binary128 for long double. Of course, I will create necessary changes to address your feedback.

I don't know what your point is bringing up that other PR, but a lack of upstream reviewer engagement (noting that, as a FreeBSD and LLVM committer, I was not aware of either PR before today) does not justify not following proper procedure, especially when it comes to ABI transitions that require a lot of care to do right.
