Subject: [PATCH] [mlir][vector] Refactor vector-transfer-flatten.mlir (nfc)
(3/n)
The main goal of this and subsequent PRs is to unify and categorize
tests in:
* vector-transfer-flatten.mlir
This should make it easier to identify the edge cases being tested (and
how they differ), remove duplicates and to add tests for scalable
vectors.
The main contributions of this PR:
1. Refactor `@transfer_read_flattenable_with_dynamic_dims_and_indices`,
i.e. move it near other tests for xfer_read, unify variable names to
match other xfer_read tests, highlight what makes this a positive
test to better contrast it with
`@transfer_write_dims_mismatch_non_zero_indices_trailing_dynamic_dim`
2. Similar changes for
`@transfer_write_flattenable_with_dynamic_dims_and_indices`.
Depends on https://github.com/llvm/llvm-project/pull/95743 and https://github.com/llvm/llvm-project/pull/95744
