[PATCH] D43956: [DebugInfo] Discard invalid DBG_VALUE instructions in LiveDebugVariables

[Bjorn Pettersson via Phabricator via llvm-commits]

Updated to replace the faulty DBG_VALUE by 'DBG_VALUE %noreg' instead of
discarding it completely (as suggested by Adrian).

Currently this has little impact, as computeIntervals will discard such
DBG_VALUE instructions anyway. But doing it like this will give the wanted
result when https://bugs.llvm.org/show_bug.cgi?id=36579 has been solved.
