vec_sral: Vector Shift Right Arithmetic

d = vec_sral(a, b)

Performs an algebraic right shift for a vector by a given number of bits. Each element of the result is obtained by shifting the corresponding element of a right by the number of bits specified by the last 3 bits of every byte of b. The bits that are shifted out are replaced by copies of the most significant bit of the element of a.

Note: The low-order 3 bits of all byte elements in b must be the same, otherwise the result is undefined.
