New Revision: 270172

Log:
Fix directory_iterator handling of DT_UNKNOWN

We need to handle DT_UNKNOWN earlier, not only during directory
recursion, so that the cached file_type value in the directory_entry
won't be used.

	* src/c++17/fs_dir.cc (_Dir::advance(bool, error_code&)): Handle
	d_type == DT_UNKNOWN immediately.
	(_Dir::should_recurse(bool, error_code&)): Remove file_type::unknown
	handling here.
	* testsuite/27_io/filesystem/iterators/caching.cc: New test.
