* elfxx-mips.c (mips_got_page_range): New structure.
(mips_got_page_entry): Likewise.
(mips_got_info): Add page_gotno and got_page_entries fields.
(mips_elf_got_per_bfd_arg): Add max_pages field. Delete
primary_count and current_count fields.
(mips_got_page_entry_hash, mips_got_page_entry_eq): New functions.
(mips_elf_pages_for_range, mips_elf_record_got_page_entry): Likewise.
(mips_elf_get_got_for_bfd): New function, split out from
mips_elf_make_got_per_bfd. Initialize the page_gotno and
got_page_entries fields when creating a new GOT structure.
(mips_elf_make_got_pages_per_bfd): New function.
(mips_elf_merge_got_with): New function, split out from
mips_elf_make_got_per_bfd. Merge page entries as well as
non-page entries. Use the minimum of max_pages and the sum
of the page_gotnos to estimate the number of page entries.
(mips_elf_merge_gots): Use the minimum of max_pages and the
bfd's page_gotno to estimate the number of page entries.
Use the above functions.
(mips_elf_multi_got): Add page entries as well as non-page entries
to the individual per-bfd GOTs. Initialize got_per_bfd_arg.max_pages.
Initialize the page_gotno and got_page_entries fields when creating
a new primary GOT. Use the minimum of pages and page_gotno when
adding the number of pages entries to local_gotno.
(mips_elf_create_got_section): Initialize the page_gotno and
got_page_entries fields of the GOT structure.
(mips_elf_rel_relocation_p, mips_elf_read_rel_addend)
(mips_elf_add_lo16_rel_addend, mips_elf_get_section_contents): New
functions, split out from...
(_bfd_mips_elf_relocate_section): ...here.
(_bfd_mips_elf_check_relocs): Record GOT page entries too.
(_bfd_mips_relax_section): Use mips_elf_get_section_contents.
(_bfd_mips_elf_always_size_sections): Use the smaller of the
loadable_size- and page_gotno-derived estimates.
