Jonas Paulsson a48ea231c0 [TargetTransformInfo] getIntrinsicInstrCost() scalarization estimation improved
getIntrinsicInstrCost() used to only compute scalarization cost based on types.
This patch improves this so that the actual arguments are checked when they are
available, in order to handle only unique non-constant operands.

Tests updates:

Analysis/CostModel/X86/arith-fp.ll
Transforms/LoopVectorize/AArch64/interleaved_cost.ll
Transforms/LoopVectorize/ARM/interleaved_cost.ll

The improvement in getOperandsScalarizationOverhead() to differentiate on
constants made it necessary to update the interleaved_cost.ll tests even
though they do not relate to intrinsics.

Craig Topper 07f1c15995 [AVX-512] Support FCOPYSIGN for v16f32 and v8f64
Summary:
This extends FCOPYSIGN support to 512-bit vectors.

I've also added tests to show what the 128-bit and 256-bit cases look like with broadcast loads.

Alexey Bataev d07c731d86 Improved cost model for FDIV and FSQRT, by Andrew Tischenko
There is a bug describing poor cost model for floating point operations:
Bug 29083 - [X86][SSE] Improve costs for floating point operations. This
patch is the second one in series of patches dealing with cost model.

Sanjay Patel d27a21874b [x86, SSE/AVX] allow 128/256-bit lowering for copysign vector intrinsics (PR30433)
This should fix:
https://llvm.org/bugs/show_bug.cgi?id=30433

There are a couple of open questions about the codegen:
1. Should we let scalar ops be scalars and avoid vector constant loads/splats?
2. Should we have a pass to combine constants such as the inverted pair that we have here?
