* elf32-mips.c (elf_mips_howto_table_rel): Change definition of
R_MIPS_PC16 to rightshift 2.
(elf_reloc_map mips_reloc_map): Map to rightshifted BFD reloc.
(bfd_elf32_bfd_reloc_type_lookup): Support
BFD_RELOC_MIPSEMB_16_PCREL_S2.
* elf64-mips.c (mips_elf64_howto_table_rel): Change definition of
R_MIPS_PC16 to rightshift 2.
(mips_elf64_howto_table_rela): Likewise.
(mips_reloc_map): Map to rightshifted BFD reloc.
* elfn32-mips.c: The same as in elf64-mips.c.
* elfxx-mips.c (mips_elf_got_for_ibfd): Typo in comment.
(mips_elf_calculate_relocation): Handle rightshifted addends for
R_MIPS_PC16.
* reloc.c (BFD_RELOC_MIPSEMB_16_PCREL_S2): New BFD relocation for
MIPS Embedded PIC. Remove superfluous empty COMMENT.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
* config/tc-mips.c (append_insn): Add handling of
BFD_RELOC_MIPSEMB_16_PCREL_S2. Avoid emitting unneeded
BFD_RELOC_16_PCREL_S2 relocs and add earlier warnings about
misaligned address and reange overflow.
(macro_build): Add handling of BFD_RELOC_MIPSEMB_16_PCREL_S2. Add
earlier warnings about misaligned address and reange overflow.
(mips_ip): Add handling of BFD_RELOC_MIPSEMB_16_PCREL_S2.
(md_apply_fix): Likewise. Fix warning output.
(tc_gen_reloc): Add handling of BFD_RELOC_MIPSEMB_16_PCREL_S2.
Allow BFD_RELOC_16_PCREL_S2 for all ABIs.
(md_convert_frag): Add handling of BFD_RELOC_MIPSEMB_16_PCREL_S2.
* gas/mips/bge.d: Reactivate external branch tests.
* gas/mips/bge.s: Likewise.
* gas/mips/bgeu.d: Likewise.
* gas/mips/bgeu.s: Likewise.
* gas/mips/blt.d: Likewise.
* gas/mips/blt.s: Likewise.
* gas/mips/bltu.d: Likewise.
* gas/mips/bltu.s: Likewise.
* gas/mips/branch-misc-2.d: New File.
* gas/mips/branch-misc-2.l: Remove.
* gas/mips/mips.exp: Adjust branch-misc-2 test.
