Refactor build_type_psymtabs_reader

Browse Source 
The new DWARF scanner needs to save the entire cutu_reader object, not
just parts of it.  In order to make this possible, this patch
refactors build_type_psymtabs_reader.  This change is done separately
because it is easy to review in isolation and it helps make the later
patches smaller.
