The source data in S+1 and S must be in IEEE754 floating-point data format.
Calculates the arc sine of a 32-bit floating-point number and places the result
in the specified result words. (The arc sine function is the inverse of the sine
function; it returns the angle that produces a given sine value between –1 and
1.)
