This template implements the "sufficient additional overloads" for two-argument `<cmath>` functions (`atan2`, `hypot`, `pow`, `fmod`, `remainder`, `copysign`, `nextafter`, `fdim`, `fmax`, and `fmin`) by calling either an intrinsic or a C library function either of which expects `double` arguments. We previously converted the arguments to `_Common_float_type_t` which is `long double` when at least one argument is `long double`, resulting in narrowing conversion warnings at `/W4`. We now convert the arguments to `double` instead of `_Common_float_type_t`. Fixes microsoft#3246
