* elf64-ppc.c (PNOP): Define.
(ppc64_elf_howto_raw): Add reloc howtos for new relocations.
(ppc64_elf_reloc_type_lookup): Translate new bfd reloc numbers.
(ppc64_elf_ha_reloc): Adjust addend for highera34 and highesta34
relocs.
(ppc64_elf_prefix_reloc): New function.
(struct ppc_link_hash_table): Add notoc_plt.
(is_branch_reloc): Add R_PPC64_PLTCALL_NOTOC.
(is_plt_seq_reloc): Add R_PPC64_PLT_PCREL34,
R_PPC64_PLT_PCREL34_NOTOC, and R_PPC64_PLTSEQ_NOTOC.
(ppc64_elf_check_relocs): Handle pcrel got and plt relocs. Set
has_pltcall for section on seeing R_PPC64_PLTCALL_NOTOC. Handle
possible need for dynamic relocs on non-pcrel powerxx relocs.
(dec_dynrel_count): Handle non-pcrel powerxx relocs.

(fixup_size): Handle new powerxx relocs.
(md_assemble): Warn for @pcrel on non-prefix insns.
Accept @l, @h and @ha on prefix insns, and infer reloc without
any @ suffix. Translate powerxx relocs to suit DQ and DS field
instructions. Include operand tests as well as opcode test to
translate BFD_RELOC_HI16_S to BFD_RELOC_PPC_16DX_HA.
(ppc_fix_adjustable): Return false for pcrel GOT and PLT relocs.
(md_apply_fix): Handle new powerxx relocs.
* config/tc-ppc.h (TC_FORCE_RELOCATION_SUB_LOCAL): Accept
BFD_RELOC_PPC64_ADDR16_HIGHER34, BFD_RELOC_PPC64_ADDR16_HIGHERA34,
BFD_RELOC_PPC64_ADDR16_HIGHEST34, BFD_RELOC_PPC64_ADDR16_HIGHESTA34,
BFD_RELOC_PPC64_D34, and BFD_RELOC_PPC64_D28.
* testsuite/gas/ppc/prefix-reloc.d,
* testsuite/gas/ppc/prefix-reloc.s: New test.
