8cc02597 - [ORC] Clear stale ElemToPendingSN entries in WaitingOnGraph. (#169747)

[ORC] Clear stale ElemToPendingSN entries in WaitingOnGraph. (#169747) WaitingOnGraph::processReadyOrFailed was not clearing stale entries from the ElemToPendingSN map. If symbols were removed from the ExecutionSession and then re-added this could lead to dependencies on the stale entries, triggering a use-after-free bug. https://github.com/llvm/llvm-project/issues/169135
