Backport from mainline
2018-01-05  Jonathan Wakely  <jwakely@redhat.com>

	PR libstdc++/83626
	* src/filesystem/ops.cc (remove(const path&, error_code&)): Do not
	report an error for ENOENT.
	(remove_all(const path&)): Fix type of result variable.
	(remove_all(const path&, error_code&)): Use non-throwing increment
	for directory iterator. Call POSIX remove directly to avoid redundant
	calls to symlink_status. Do not report errors for ENOENT.
