Kalle Raiskila 8b2f70125f Make SPU backend handle insertelement and 
store for "half vectors"

Kalle Raiskila 622f8eb981 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.
