VMOVL, V{Q}MOVN, VQMOVUN

VMOVL (Vector Move Long) takes each element in a doubleword vector, sign or zero extends them to twice their original length, and places the results in a quadword vector.

VMOVN (Vector Move and Narrow) copies the least significant half of each element of a quadword vector into the corresponding elements of a doubleword vector.

VQMOVN (Vector Saturating Move and Narrow) copies each element of the operand vector to the corresponding element of the destination vector. The result element is half the width of the operand element, and values are saturated to the result width.

VQMOVUN (Vector Saturating Move and Narrow, signed operand with Unsigned result) copies each element of the operand vector to the corresponding element of the destination vector. The result element is half the width of the operand element, and values are saturated to the result width.
