Vector Fixed-Point Multiply and Subtract

The product of fixed-point elements in vector c (four signed 32-bit integer numbers) by fixed-point elements in vector b (four signed 32-bit integer numbers) are subtracted from the fixed-point elements in vector a (four signed 32-bit integer numbers). The multiplication result is not saturated, i.e. exact (-1) * (-1) = 1 is subtracted from the destination. The saturated fixed-point results are stored back to vector a.
