however it is not practical to add two or more sets of 12-bit
prefixes into a single instruction.
A compromise is to provide a Swizzle "Move": one such move is
-then required for each operand to a subsequent instruction.
-The encoding for this instruction embeds static predication into the
-swizzle as well as constants 1/1.0 and 0/0.0

An extremely important aspect of 3D GPU workloads is that the source
and destination subvector lengths may be *different*. A vector of
