Subject: [PATCH] Switch users of SmallMap to use SmallDenseMap instead.

The most important change here is that the destructor and copy
constructor for StoredDeclsList will now reliably be run. Previously,
the destructors at least were missed in some cases. See the LLVM commits
discussions for why SmallMap is broken and going away.
