I may have mixed it up with FloatConsts or DouleConsts but I'm pretty
sure there was a dependency at one point. The main thing is that we've
checked and all is okay.
I skimmed over the webrev and it looks good to me (I didn't check ilogb
closely but I assume it has just moved without any changes). One minor
comment is that I'm not sure that it's worth add the bug number to
IeeeRecommendedTests as the change doesn't introduce any tests or fix
issues that would be interested in check back on in the future.
