This patch could be rewritten in terms of the DebugVariable class being discussed in D70318 <https://reviews.llvm.org/D70318>. We'd still need to group the DebugVariables by { Variable, InlinedAt } to let us search for overlaps so it looks to me like the only benefit would be unification of representations across passes (which is important IMO).

At a glance I'm not sure how much work this would require.
