[CostModel][X86] Add partial CostKinds handling for funnelshifts/rotates
This mainly just adds costs for the targets where we have actual funnelshift/rotate instructions (VBMI2/XOP etc.) - the cases where we expand still need addressing, although for many the default shift+or expansion, especially for uniform cases, isn't that bad.
This was achieved with the 'cost-tables vs llvm-mca' script D103695
