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

[Jeremy Morse via Phabricator via llvm-commits]

Address the loop matter I mention at the end of the review summary -- I've convinced myself that we only need to validate very simple loops in this context, because LLVMs tail-duplicator doesn't substantially rewrite functions, it only duplicates bits of it.

I've added an extra test for finding the value of DBG_PHIs even if there's a loop in between the DBG_PHIs and their uses.
