Subject: [PATCH 1/2] [mlir][vector] Add tests xfer-permute-lowering (nfc)(2/n)
Adds more tests to:
* vector-transfer-permutation-lowering.mlir
Specifically, adds tests for:
* out-of-bounds access for the `TransferWritePermutationLowering`
pattern
* in-bounds access for `TransferWriteNonPermutationLowering` +
`TransferWritePermutationLowering`
Also renames `@permutation_with_mask_xfer_write_fixed_width` as
`@xfer_write_non_transposing_permutation_map`.
This is a part of a larger effort to make sure that all key cases for
patterns under populateVectorTransferPermutationMapLoweringPatterns
(*) are tested. I also want to make sure that tests use consistent
function and variable names.
(*) transform.apply_patterns.vector.transfer_permutation_patterns in
TD parlance)
Depends on #96031
