Kalle Raiskila 21615cb06e Add preliminary v2i32 support for SPU backend. As there are no
such registers in SPU, this support boils down to "emulating" 
them by duplicating instructions on the general purpose registers. 

This adds the most basic operations on v2i32: passing parameters,
addition, subtraction, multiplication and a few others.
