<pre>This was originally considered part of PR43272, because it's part of the
virtual file system tests, but the issue here is not VFS. On Windows, the
tests fails before VFS is applied. Instead, it's caused by failure to
recognize that two paths to the same file (via a symlink) actually refer to the
same file.
Excerpt from `$ ninja check-clang-vfs`:
FAIL: Clang :: VFS/subframework-symlink.m (16 of 20)
