Add support for the TLV relocation generated by LLVM for x86_64 MACH-O targets.
PR 23297
* mach-o-x86-64.c (x86_64_howto_table): Add entry for
BFD_RELOC_MACH_O_X86_64_RELOC_TLV.
(bfd_mach_o_x86_64_canonicalize_one_reloc): Handle the new reloc.
(bfd_mach_o_x86_64_swap_reloc_out): Likewise.
* reloc.c (BFD_RELOC_MACH_O_X86_64_TV): New entry.
* bfd-in2.h: Regenerate.
* libbfd.h: Regenerate.
