Vector Signed Horizontal Add
The sign-extended odd elements in vector a
(four signed 32-bit integer numbers)
are added to the sign-extended even elements in vector b
(four signed 32-bit integer numbers)
producing a result twice the size of the input operands.
The result is written to vector (two signed 64-bit integer numbers).
