  Changed paths:
    M llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp
    A llvm/test/DebugInfo/assignment-tracking/X86/assignment-tracking-not-enabled.ll

  Log Message:
  -----------
  [Assignment Tracking][SelectionDAG] Downgrade dbg.assigns to dbg.values if assignment tracking is not enabled

We shouldn't be able to reach this code path from source code but this provides
a better fail-safe than asserting. The result of the downgrade is a degraded
debugging experience, but it is better than nothing.
