  Log Message:
  -----------
  [mlir][sparse] accept affine subscripts in outer dimensions of dense memrefs

This relaxes vectorization of dense memrefs a bit so that affine expressions
are allowed in more outer dimensions. Vectorization of non unit stride
references is disabled though, since this seems ineffective anyway.
