VSLI (Vector Shift Left and Insert) takes each
element in a vector, left shifts them by an immediate value, and
inserts the results in the destination vector. Bits shifted out
of the left of each element are lost.
VSRI (Vector Shift Right and Insert) takes each
element in a vector, right shifts them by an immediate value, and
inserts the results in the destination vector. Bits shifted out
of the right of each element are lost.
