[PATCH] D86814: [DebugInstrRef][3/3] Follow DBG_PHI instructions through LiveDebugValues.

[Jeremy Morse via Phabricator via llvm-commits]

Ping and refresh of this patch; I've replaced a multimap with a sorted vector, used a class to store information about seen DBG_PHIs, and twiddled some documentation.

See the main review comment, while there's tons of C++ in this patch, it's boilerplate to deploy LLVMs existing SSA Updater.
