	* 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.
