* nrun.c (main): Print the simulator statistics only in
        verbose mode.
        * hw-properties.h (hw_find_integer_array_property): Fix
        prototype (use signed_cell).

/* Manipulate the properties belonging to a given device.
HW_ADD_* will, if the property is not already present, add a
property to the device. Adding a property to a device after it has
been created is a checked run-time error (use HW_SET_*).
HW_SET_* will always update (or create) the property so that it has
the specified value. Changing the type of a property is a checked
run-time error.
FIND returns the specified properties value. It is a checked
runtime error to either request a nonexistant property or to
request a property using the wrong type. Code locating a property
should first check its type (using hw_find_property above) and then
obtain its value using the below.
