[PATCH] D154905: [clang] Implement `PointerLikeTraits` for `{File,Directory}EntryRef`

[Ben Langmuir via Phabricator via cfe-commits]

Comment at: clang/include/clang/Basic/DirectoryEntry.h:211

+  static constexpr int NumLowBitsAvailable = 3;
+};
----------------
I suggest not hard-coding it if you can get away with it; maybe `PointerLikeTypeTraits<clang::DirectoryEntryRef::MapEntry *>::NumLowBitsAvailable`? I think 3 could be wrong on a 32-bit platform for example.
