-// Function Set2OperandsFromInstr
-// Function Set3OperandsFromInstr
-// 
-// Purpose:
-// 
-// For the common case of 2- and 3-operand arithmetic/logical instructions,
-// set the m/c instr. operands directly from the VM instruction's operands.
-// Check whether the first or second operand is 0 and can use a dedicated
-// "0" register.
-// Check whether the second operand should use an immediate field or register.
-// (First and third operands are never immediates for such instructions.)
-// 
-// Arguments:
-// canDiscardResult: Specifies that the result operand can be discarded
-//                  by using the dedicated "0"
-// 
-// op1position, op2position and resultPosition: Specify in which position
-//                  in the machine instruction the 3 operands (arg1, arg2
-//                  and result) should go.
-// 
-// RETURN VALUE: unsigned flags, where
-//     flags & 0x01    => operand 1 is constant and needs a register
-//     flags & 0x02    => operand 2 is constant and needs a register
