llvm version

Is the version of llvm in the tree really 13.0.0?

The MesaLib sources (not MesaLib.old) in xsrc contain this:

#if LLVM_VERSION_MAJOR >= 13
   llvm::Module *M = llvm::unwrap(MRef);
   M->setOverrideStackAlignment(align);
#endif

The setOverrideStackAlignment() member function isn't defined in
src/external/apache2/llvm/dist/llvm/include/llvm/IR/Module.h, it is
defined in llvm 15.0.7 in pkgsrc.
