It turned out much nicer when I switched on the builtin ID first, so there's
not much left to share. This could be extracted to a `bool
ComparisonFunction(unsigned BuiltinID, const APFloat &LHS, const APFloat
&RHS)`, but I don't know where I could put that so that ExprConstant.cpp and
InterpBuiltin.cpp could both access it
