These issues haven't been resolved yet, but the discussion is correct
that these operations allocate memory, so the proposed resolutions are
correct.

	* include/bits/fs_dir.h (directory_iterator): Remove noexcept from
	constructors and increment member (LWG 3013).
	(recursive_directory_iterator): Likewise.
	* include/bits/fs_ops.h (copy, copy_file, create_directories)
	(is_empty, remove_all): Remove noexcept (LWG 3013 and LWG 3014).
	* src/filesystem/std-dir.cc (directory_iterator::increment)
	(recursive_directory_iterator::increment): Remove noexcept.
	* src/filesystem/std-ops.cc (copy, copy_file, create_directories)
	(is_empty, remove_all): Remove noexcept

Tested powerpc64le-linux, committed to trunk.
