libstdc++: Improve exceptions thrown from fs::temp_directory_path
Currently the throwing overload of fs::temp_directory_path() will
discard the path that was obtained from the environment. When it fails
because the path doesn't resolve to a directory you get an unhelpful
error like:
filesystem error: temp_directory_path: Not a directory
It would be better to also print the path in that case, e.g.
filesystem error: temp_directory_path: Not a directory [/home/bob/tmp]
libstdc++-v3/ChangeLog:
* src/c++17/fs_ops.cc (fs::temp_directory_path()): Include path
in exception.
(fs::temp_directory_path(error_code&)): Rearrange to more
closely match the structure of the first overload.
* src/filesystem/ops.cc (fs::temp_directory_path): Likewise.
* testsuite/27_io/filesystem/operations/temp_directory_path.cc:
Check that exception contains the path.
* testsuite/experimental/filesystem/operations/temp_directory_path.cc:
Likewise.
