Eric Anholt 6a88ada7e8 Add support for swizzle control on source operands.
This required restructuring to store source operands in a new structure rather
than being stored in instructions, as swizzle is align16-only and shares
storage with other fields for align1 mode.

These changes were not tested on real programs using swizzle.
