  -----------
  [mlir] Use VectorTransferPermutationMapLoweringPatterns in VectorToSCF

VectorTransferPermutationMapLoweringPatterns can be enabled via a pass option. These additional patterns lower permutation maps to minor identity maps with broadcasting, if possible, allowing for more efficient vector load/stores. The option is deactivated by default.
