Improve allocation of memory for byte-code array and literal identifiers hash table.

Browse Source 
- literal identifiers hash table and byte-code array are now allocated in one heap block instead of four blocks;
 - memory regions with the hash tables and arrays are now linked into linked list using headers at start of the regions instead of using array_list.
