-// Function Set2OperandsFromInstr
-// Function Set3OperandsFromInstr
-// 
-// 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.
-//
