`deleteAssignmentMarkers(const Instruction *Inst)` does exactly as you'd expect - it deletes any dbg.assign intrinsics linked to `Inst`.

I'll fold this into the previous patch (D132224 <https://reviews.llvm.org/D132224>) when landing them, but I wanted to keep the review separate as that one has already been accepted.
