//------------------------------------------------------------------------
// 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
//------------------------------------------------------------------------
