Revision addressing some comments and cutting down on datastructure sizes. Note that I've deleted two tests here: with the additional conflict resolution information, there are some non-live DBG_VALUEs that can be fixed. Specifically, CR_Erase indicating "this was a redundant and dead copy of the other vreg that we're erasing" is something that can be safely resolved.
