[PATCH] D41794: [X86] Improve AVX1 shuffle lowering for v8f32 shuffles where the low half comes from V1 and the high half comes from V2 and the halves do the same operation

currently you call  lowerVectorShuffleSplitLowHigh() form lowerV8F32VectorShuffle() only.

In order to cover v4f64, v4i64, v8i32 types, 
can you add a call  to lowerVectorShuffleSplitLowHigh() to other 256 bit vector lowering functions?
