To properly support the matrix intrinsics on, e.g., 32-bit platforms (without the need to emit `libc` calls), `LowerMatrixIntrinsics` pass should generate code that performs strided index calculations using the same pointer bit-width as the matrix pointers, as determined by the data layout. This patch updates the `LowerMatrixInstrics` transform to make this the case. PR: https://github.com/llvm/llvm-project/pull/162646
