[DAG] Add BuildVectorSDNode::getRepeatedSequence helper to recognise multi-element splat patterns
Replace the X86 specific isSplatZeroExtended helper with a generic BuildVectorSDNode method.
I've just used this to simplify the X86ISD::BROADCASTM lowering so far (and remove isSplatZeroExtended), but we should be able to use this in more places to lower to complex broadcast patterns.
