Previously SelectionDAGBuilder used ABI alignment for compressstore/expandload. This patch allows SelectionDAGBuilder to use parameter alignment like vp intrinsics. This does not follow the original code to default use vector type alignment, since it is possible implemented to unaligned vector alignment.
