libstdc++: Reuse double overload of __convert_to_v if possible
For targets where double and long double have the same representation we
can reuse the same __convert_to_v code for both types. This will
slightly reduce the size of the compiled code in the library.
libstdc++-v3/ChangeLog:
* config/locale/generic/c_locale.cc (__convert_to_v): Reuse
double overload for long double if possible.
