Missing commit update of the submodule

Retested GOWA, GOW3 and P5 with this PR to see if it would make a difference to the minor performance regression in those games compared to the final pre-LLVM16 master, unfortunately it does not.

Whatever you did with that latest commit, it worked wonders.

Performance is back to pre-LLVM 16 master levels with GOWA, and almost there with GOW3. P5 is still slower than pre-LLVM 16, but got a performance improvement from it too compared to previous PR commit build.
