I take to that we must support one or more compilers that do not support C++14 extended constexpr and hence had to rewrite this function to have a single return statement.

Right. At least, WebKitGTK+ needs to support GCC 4.9 now, which does not support C++14 relaxed constexpr.
Once C++14 relaxed constexpr is allowed, the above code will be much simplified.
