Vector Shift Left Double by Words

Endian considerations

This intrinsic is not endian-neutral, so uses of vec_sldw in big-endian code must be rewritten for little-endian targets.

The concatenation of a and b is done in big-endian fashion (left to right), and the shift is always to the left. This will generally produce surprising results for little- endian targets.
