[X86][Costmodel] `getReplicationShuffleCost()`: implement cost model for 32/64 bit-wide elements with AVX512F

[lebedev.ri]

Summary

This models lowering to vpermd/vpermq/vpermps/vpermpd,
that take a single input vector and a single index vector,
and are cross-lane. So far i haven't seen evidence that
replication ever results in demanding more than a single
input vector per output vector.

This results in *shockingly* lesser costs :)

3741–3747

Yes, we should not need to override this, but then it does not compile,
it seems like that ^ override hides base implementation of this method.
So far my attempts at fixing this have not been successful.

3702–3704

I guess two sources of demanded elts was a wrong choice,
DemandedSrcElts is implied by DemandedReplicatedElts,
yet DemandedSrcElts provides less knowledge than DemandedReplicatedElts,
and changing DemandedReplicatedElts to DemandedIndices
would also be lossy. I'll drop DemandedSrcElts later.

[lebedev.ri]

Tidy up the code somewhat, NFC.

[lebedev.ri]

Ok, and implement the fast-path that assumes that all the non-trivial invariants hold,
but keep the original complex code in with-asserts mode and verify that results match.

[lebedev.ri]

The rough roadmap for the planned follow-ups:

1. i16 if +BWI
2. i8 if +VBMI
3. i16 ?ext -> i32 -> trunc i16 if -BWI
4. i8 ?ext -> i16 -> trunc i8 if -VBMI +BWI
5. i8 ?ext -> i32 -> trunc i8 if -VBMI -BWI
6. i1 ?ext -> i8 -> trunc i1 if +VBMI
7. i1 ?ext -> i16 -> trunc i1 if -VBMI +BWI
8. i1 ?ext -> i32 -> trunc i1 if -VBMI -BWI
9. ???
10. PROFIT!

[lebedev.ri]

Rebased after refactoring baseline interface, NFC.

Is this really useful?

3730

can't we extract the length of seq() ?

3742

I'm really torn over whether this should be in the method or not :( I understand its use but its a LOT of debug code.

[lebedev.ri]

@RKSimon thanks for taking a look!
Dropped debug code, i've convinced myself that this is trivially true for AVX512 shuffles, given that the replication factor is integral.

Spelling the exact same thing over and over seems bound to do it wrong at some point.
I can inline if you insist, but it seemed more concise this way.

We're not using the cost at all. just the legalized type?

[lebedev.ri]

llvm/lib/Target/X86/X86TargetTransformInfo.cpp

Could you please clarify, are you asking to change this to

MVT LegalReplicatedVecTy =
      TLI->getTypeLegalizationCost(DL, ReplicatedVecTy).second;

, or asking why we don't use the cost?
I'm mainly not sure why that cost is there or how i should use it here.
We don't need to legalize the input, it already as,
we just need to know how it's laid out (how many ?MM vectors), i believe?

[RKSimon]

Yeah, you're right - LGTM
