[mlir][Vector] Update lowering of vector ops to llvm intrinsics to use row-major.
Summary:
LLVM matrix intrinsics recently introduced an option to support row-major mode.
This matches the MLIR vector model, this revision switches to row-major.
A corner case related to degenerate sizes was also fixed upstream.
This revision removes the guard against this corner case.
A bug was uncovered on the output vector construction which this revision also fixes.
Lastly, this has been tested on a small size and benchmarked independently: no visible performance regression is observed.
In the future, when matrix intrinsics support per op attribute, we can more aggressively translate to that and avoid inserting MLIR-level transposes.
This has been tested independently to work on small matrices.
