Implement P1989R2 which adds a range constructor for `string_view`. Adjust `operator/=` in `path` to avoid atomic constraints caching issue getting provoked from this PR. Add defaulted template argument to `string_view`'s "sufficient overloads" to avoid mangling issues in `clang-cl` builds. It is a MSVC mangling bug that this works around.
