	* elfxx-mips.c (mips_got_page_ref): New structure.
	(mips_got_page_entry): Use a section rather than a (bfd, symndx)
	pair to represent the anchor point.
	(mips_got_info): Add a got_page_refs field.
	(mips_elf_link_hash_table): Add a sym_cache field.
	(mips_got_page_ref_hash, mips_got_page_ref_eq): New functions.
	(mips_got_page_entry_hash, mips_got_page_entry_eq): Update for
	new anchor representation.
	(mips_elf_create_got_info): Create got_page_refs rather than
	got_page_entries.
	(mips_elf_record_got_page_ref): New function.
	(mips_elf_pages_for_range): Move further down file.
	(mips_elf_record_got_page_entry): Likewise.  Take a got as argument.
	Use a section rather than a (bfd, symndx) pair to represent the
	anchor point.
	(mips_elf_resolve_got_page_ref): New function.
	(mips_elf_resolve_final_got_entries): Use it to populate
	got_page_entries.
	(_bfd_mips_elf_check_relocs): Call mips_elf_record_got_page_ref
	rather than mips_elf_record_got_page_entry.  Only nullify h
	afterwards.
	(mips_elf_lay_out_got): Call mips_elf_resolve_final_got_entries
	earlier.
