[X86][Costmodel] Load/store i64 Stride=4 VF=16 interleaving costs
A few more tuples are being queried after D111546. Might be good to model them, They all require a lot of manual assembly surgery. 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/9bnKrefcG - for intels `Block RThroughput: =40.0`; for ryzens, `Block RThroughput: =16.0` So could pick cost of `40` For store we have: https://godbolt.org/z/5s3s14dEY - for intels `Block RThroughput: =40.0`; for ryzens, `Block RThroughput: =16.0` So we could pick cost of `40`. I'm directly using the shuffling asm the llc produced, without any manual fixups that may be needed to ensure sequential execution.
