This revision is now accepted and ready to land.

I still think the docs need //some// adjustment.
And not for all arches the there are full set of tests (i.e. one with `"no-signed-zeros-fp-math"="true"`, one without).
But this is a regression, so i'd guess that can be iterated later on.

It would be best if someone else could agree/disagree, but other than that, LG.
