message: Properly namespace createLowerAffineApply
  This was missing from the original commit.  The implementation of
  createLowerAffineApply was defined in the default namespace but declared in the
  `mlir` namespace, which could lead to linking errors when it was used.  Put the
  definition in `mlir` namespace.
