 * Collect array-models, we need them to replace identifiers later. Princess models arrays as
 * plain numeric "memory-addresses", and the model for an array-access at one of the addresses is
 * the array-content. Example: "arr[5]=123" is modeled as "{arr=0, select(0,5)=123}" or "{arr=0,
 * store(0,5,123)=0}", where "0" is the memory-address. The returned mapping contains the mapping
 * of "0" (=address) to "arr" (=identifier).
