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.

-Subject: [PATCH 2/3] Fix build with musl libc
-
-On musl libc the fopen64 and fopen are the same thing, but for
-compatibility they have a `#define fopen64 fopen`. Same applies for
-fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.

-This patch ensures that 64-bit PowerPC musl targets use ELFv2 ABI on both

-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.
