For load we have:

The only sched models that for cpu's that support avx2
but not avx512 are: haswell, broadwell, skylake, zen1-3
Here for `store` pattern we are starting to have spilling,
so accurate modelling may be problematic,
although if i drop the spilling, the measurements don't change.
For load we have:
https://godbolt.org/z/1oTTnncbx - for intels `Block RThroughput: =16.0`; for ryzens, `Block RThroughput: <=8.0`
So pick cost of `16`.
For store we have:
https://godbolt.org/z/1oTTnncbx - for intels `Block RThroughput: =16.0`; for ryzens, `Block RThroughput: =8.0`
So pick cost of `16`.
I'm directly using the shuffling asm the llc produced,
without any manual fixups that may be needed
to ensure sequential execution.

For this tuple, measuring becomes problematic since there's a lot of spilling going on,
but apparently all these memory ops do not affect worst-case estimate at all here.
