[PATCH] D79718: [x86][CGP] enable target hook to sink funnel shift intrinsic's splatted shift amount

[Sanjay Patel via Phabricator via llvm-commits]

Patch updated:
I accidentally left off the header file comment diffs. I think those updates still make sense because we're expanding the usage of the existing TLI hook to include funnel shifts. Not sure yet if we can remove that isVectorShiftByScalarCheap() hook entirely since it is used in another spot in CGP.
