Oh dear, TypeInfo_Invariant is indeed used once in the the deprecated,
undocumented part of std.format. And it directly checks for the
occurrence of "Invariant" in the mangled name, something that would
inevitably break if we renamed the class.

Still, I feel that oddities like this decrease the "hackability" of
the D tool chain – maybe we should just stick a big red notice in the
code comments?
