I am guessing that you'd like to use 2. for `vector.outerproduct` to lower to SME's MOPA instructions, e.g. [FMOPA](https://developer.arm.com/documentation/ddi0602/2021-06/SME-Instructions/FMOPA--non-widening---Floating-point-outer-product-and-accumulate-)? I am still wondering whether mixing 1. and 2. is the right approach.

That's correct, I want to lower `vector.outerproduct` directly to intrinsics, at least initially as this seems to work. But this would also open this up for other ops where possible.

Thanks for reviewing!
