SHIFTA— Right shift with fill
SHIFTAreturns a value corresponding to I with all of the bits shifted right by SHIFT places. If the absolute value of SHIFT is greater than
BIT_SIZE(I), the value is undefined. Bits shifted out from the right end are lost. The fill is arithmetic: the bits shifted in from the left end are equal to the leftmost bit, which in two's complement representation is the sign bit.
