user/llvm8: Move to legacy/

We don't need LLVM 8 in-tree any more.  The last dependent was Qt
Creator.  LLVM 14 is the new hotness.

Closes: #460, #871

-Subject: [PATCH] SCC: Allow ReplaceNode to safely support insertion
-
-If scc_iterator::ReplaceNode is inserting a new entry in the map,
-rather than replacing an existing entry, the possibility of growing
-the map could cause a failure.  This change safely implements the
-insertion.
