[X86][Costmodel] Load/store i32 Stride=3 VF=32 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/s5b6E6jsP - for intels `Block RThroughput: <=32.0`; for ryzens, `Block RThroughput: <=24.0` So could pick cost of `32` For store we have: https://godbolt.org/z/efh99d93b - for intels `Block RThroughput: <=48.0`; for ryzens, `Block RThroughput: <=32.0` So we could pick cost of `48`. I'm directly using the shuffling asm the llc produced, without any manual fixups that may be needed to ensure sequential execution.
