    Change the key type in psym_index_map
    
    In order to change the DWARF index writer to avoid partial symtabs,
    this patch changes the key type in psym_index_map (and renames that
    type as well).  Using the dwarf2_per_cu_data as the key makes it
    simpler to reuse this code with the new indexer.
