 Fix for Google Ref: b/8028506
 
 Calling find_AT_string can resize the debug_str hash table, even if the
 string is already present in the hash table--go figure. So after indices
 have been assigned, and the hash table is exactly three-quarters full,
 calling find_AT_string is verboten.
 
 This change moves some calls around such that the above scenario never
 happens, all strings will be found and assigned prior to indices being
 assigned.
