[PATCH] D118715: [DebugInfo][InstrRef] Fix a tombstone-in-DenseMap crash from D117877

[Stephen Tozer via Phabricator via llvm-commits]

StephenTozer added a comment.

Seems reasonable as a fix to me. Is there any particular reason that the undef value test couldn't exist within the original function, or are they separated to look cleaner? YMMV and I don't feel strongly either way, so LGTM.
