[SLP]Fix cost of the broadcast buildvector/gather.

[ABataev]

Summary

Need to include the cost of the initial insertelement to the cost of the
broadcasts. Also, need to adjust the cost of the gather/buildvector if
the element is ionserted into poison/undef vector.

How much work to avoid the default values on all the target impl? We don't do the same for Index.

[ABataev]

Remove default values in target-specific implementations.

These costs are definitely not free - integer scalars still need to be transfered from gpr to xmm registers.

[ABataev]

Address comments, fixed the cost of insertelement for integer constant.

constang -> constant

Switch order in case Op1 is null:

if ( isa_and_nonnull<Constant>(Op1) && Op1->getType()->isIntegerTy())

Something is still wrong - you have a more expensive cost to insert a i64 into [0] than [1] - for SSE4 they should both be cost = 1

Should this comment also be removed? It seems like the code has been removed?

[ABataev]

llvm/lib/Target/X86/X86TargetTransformInfo.cpp

4365–4369

No, it is not removed, the related code is all in the same lambda IsCheapPInsrPExtrInsertPS

[fhahn]

llvm/lib/Target/X86/X86TargetTransformInfo.cpp

4365–4369

Ah, but it documents the logic in the helper function now, which is used in multiple places. Should it not be moved there?

Also, shouldn't the 2 sentences be merged? At the moment, the wording seems to imply that pinsr/pextr XMM <-> GPR is relatively cheap on all targets AND insertps is relatively cheap on all targets., whereas it should be OR?

[ABataev]

Ok, will move it to the lambda
