Simon Pilgrim a5e129ccde [CostModel][X86] getVectorInstrCost - correctly cost v4f32 insertelement into index 0
This is just the MOVSS instruction (SSE41 INSERTPS is still necessary for index != 0)

This exposed an issue in VectorCombine::foldInsExtFNeg - we need to use the more general SK_PermuteTwoSrc shuffle kind to allow getShuffleCost to match other shuffle kinds (not just SK_Select).
