[X86][AVX] Use lowerShuffleAsLanePermuteAndSHUFP to lower binary v4f64
shuffles.
Only perform this if we are shuffling lower and upper lane elements
across the lanes (otherwise splitting to lower xmm shuffles would be
better).
This is a regression if we shuffle build_vectors due to getVectorShuffle
canonicalizing 'blend of splat' build vectors, for now I've set this not
to shuffle build_vector nodes at all to avoid this.

Fix "pointer is null" static analyzer warnings. NFCI.
Use cast<> instead of dyn_cast<> and move into its users where its
dereferenced immediately.
