CreateArray

The arrays are virtual. IDA allocates space for and keeps only the specified
elements of an array. Array index is 32-bit long. Actually, each array
may keep a set of strings and a set of long(32bit) values.

** create array
        arguments:      name - name of array. There are no restrictions
                               on the name (its length should be less than
                               120 characters, though)
        returns:        -1 - can't create array (it already exists)
                        otherwise returns id of the array
