### Description This PR builds on #99872. It implements a minimal version of function body vector unrolling to convert vector types into 1D and with a size supported by SPIR-V (2, 3 or 4 depending on the original dimension). The ops that are currently supported include those with elementwise traits (e.g. `arith.addi`), `vector.reduction` and `vector.transpose`. This PR also includes new LIT tests that only check for vector unrolling. ### Future Plans - Support more ops --------- Co-authored-by: Jakub Kuderski <kubakuderski@gmail.com>
