Use _bfd_mips_elf_generic_reloc for R_MIPS_GOT16 as well.
(mips_elf64_hi16_reloc, mips_elf64_got16_reloc): Delete.
(mips_elf64_shift6_reloc): Remove special case. Use
_bfd_mips_elf_generic_reloc instead of returning bfd_reloc_continue.
* elfn32-mips.c (prev_reloc_section): Delete.
(prev_reloc_address, prev_reloc_addend): Delete.

(_bfd_mips_elf_relocate_section): Don't apply the howto rightshift
on top of the usual high-part shift. Don't shift the addend right
before calling mips_elf_calculate_relocation.
