The only sched models that for cpu's that support avx2
but not avx512 are: haswell, broadwell, skylake, zen1-3
For load we have:
https://godbolt.org/z/zdz5Ga6fs - for intels `Block RThroughput: =7.0`; for ryzens, `Block RThroughput: <=6.0`
So pick cost of `7`.
For store we have:
https://godbolt.org/z/qn71513ac - for intels `Block RThroughput: =11.0`; for ryzens, `Block RThroughput: <=8.0`
So pick cost of `11`.
I'm directly using the shuffling asm the llc produced,
without any manual fixups that may be needed
to ensure sequential execution.
