DebugIR: Remove empty directories from SVN

Use unique_ptr to remove some explicit deletes on some error case returns. At least one spot of weird ownership passing that needs some future cleanup.

Constify some things in preparation for CodeGenSubRegIndex to be stored by value in their container, removing the indirection

Use deque<T> rather than vector<T*> since it provides the same invalidation semantics (at least when removal is not needed) without the extra indirection/ownership complexity

Order matters for this container, it seems (using a forward_list and
replacing the original push_backs with emplace_fronts caused test
failures). I didn't look too deeply into why.

(& in retrospect, I might go back & change some of the forward_lists I
introduced to deques anyway - since most don't require removal, deque is
a more memory-friendly data structure (moderate locality while not
invalidating pointers))

The previous patch had effect, but missed this one. It seems MSVC
gets ADL-confused by the calls where the first argument is a function call?

Revert r222957 "Replace std::map<K, V*> with std::map<K, V> to handle ownership and deletion of the values."

Upon further review I think the MultiClass is being copied into the map instead of being moved due to the copy constructor on the nested Record type. This ultimately got exposed when the vector in DefPrototype vector was changed to hold unique_ptrs in another commit. This caused gcc 4.7 to fail due to the use of the copy constructor on unique_ptr with the error pointing back to one of the insert calls from this commit. Not sure why clang was able to build.

This reverts commit 710cdf729f84b428bf41aa8d32dbdb35fff79fde.
