I think we can safely scratch frexp & remquo from the list: I double checked
that the middle-end functions correctly compute the constants.
(It seems more a problem with my C++ test snippets in Comments #1 / #2: I
suppose any definition of such functions isn't viable for constexpr, because
the body has to assign the pointed integer additionally to returning a value...
If Jason could confirm it would be great)
