PR 10880
* object.h (class Object): Add is_needed and set_is_needed
methods. Add is_needed_ field. Make bool fields into bitfields.
* symtab.cc (Symbol_table::set_dynsym_indexes): If a symbol is
defined in a dynamic object and referenced by a regular object,
set is_needed for the dynamic object.
* layout.cc (Layout::finish_dynamic_section): Don't add DT_NEEDED
if the file is marked with as_needed and it is not needed.
