Discussion:
All the defaulted operator==s in 17.11.2 [cmp.categories] are currently specified as:
friend constexpr bool operator==(strong_ordering v, strong_ordering w) noexcept = default;
But the rule for defaulting operator== requires that the arguments be const&. All
five should all look like:
friend constexpr bool operator==(const strong_ordering& v, const strong_ordering& w) noexcept = default;

Our preference is for CWG to fix this. JW to provide wording in case CWG cannot.
