ExtendedAddSubShiftOp

public ExtendedAddSubShiftOp(AArch64ArithmeticOp op,
                             AllocatableValue result,
                             AllocatableValue src1,

                             int shiftAmt)

Computes result = src1 + extendType(src2) << shiftAmt.

Parameters:

extendType - defines how src2 is extended to the same size as src1.

shiftAmt - must be in range 0 to 4.
