addVariableLocationOps()

void DbgVariableIntrinsic::addVariableLocationOps	(	ArrayRef< Value * >	NewValues,
		DIExpression *	NewExpr
	)

Adding a new location operand will always result in this intrinsic using an ArgList, and must always be accompanied by a new expression that uses the new operand.
