  Log Message:
  -----------
  [DebugInfo] [SelectionDAG] Fix handling of duplicate dbg values (#86598)

Before this fix, a duplicate llvm.dbg.value intrinsic referring to an
argument, after an alloca, would be generated with `$noreg`, losing
debug information. Instead, we silently drop the second debug info, so
it doesn't break the first one.
