This patch is similar to the FileEntryRef patch, in that it introduces a parallel API to get the directory entry, without replacing all uses. The immediate use in the patch fixes the issue where a file manager was reused in clang-scan-deps, but reported an different file path whenever a framework lookup was done through a symlink.
