* object.h (Sized_relobj::View_size, Sized_relobj::Views): Change
from private to protected to allow access by child class.
(Sized_relobj::do_relocate_sections): New method declaration.
(Sized_relobj::relocate_sections): Virtualize.
* reloc.cc (Sized_relobj::do_relocate_sections): Rename from
Sized_relobj::relocate_sections. Instantiate template explicitly
for different target sizes and endianity.
