[libclc] [libclc] Fix unresolved reference to missing table (PR #133691)

[Fraser Cormack via cfe-commits]

https://github.com/frasercrmck created https://github.com/llvm/llvm-project/pull/133691

Splitting the 'ln_tbl' into two in db98e292 wasn't done thoroughly enough as some references to the old table still remained. This commit fixes the unresolved references by updating to the new split table.
