ELF: Move tlsdesc_plt/tlsdesc_got to elf_link_hash_table
All ELF backends with TLS descriptor support have
/* The offset into splt of the PLT entry for the TLS descriptor
resolver. Special values are 0, if not necessary (or not found
to be necessary yet), and -1 if needed but not determined
yet. */
bfd_vma tlsdesc_plt;
/* The GOT offset for the lazy trampoline. Communicated to the
loader via DT_TLSDESC_GOT. The magic value (bfd_vma) -1
indicates an offset is not allocated. */
bfd_vma tlsdesc_got;
in symbol hash entry. Move tlsdesc_plt/tlsdesc_got to elf_link_hash_entry
to reduce code duplication.
* elf-bfd.h (elf_link_hash_entry): Add tlsdesc_plt and
tlsdesc_got.
* elf32-arm.c (elf32_arm_link_hash_table): Remove tlsdesc_plt
and dt_tlsdesc_got.
(elf32_arm_size_dynamic_sections): Updated. Clear
root.tlsdesc_plt for DF_BIND_NOW.
(elf32_arm_finish_dynamic_sections): Updated.
(elf32_arm_output_arch_local_syms): Likewise.
* elf32-nds32.c (nds32_elf_size_dynamic_sections): Updated.
Clear root.tlsdesc_plt for DF_BIND_NOW.
(nds32_elf_finish_dynamic_sections): Updated.
* elf32-nds32.h (elf_nds32_link_hash_table): Remove
dt_tlsdesc_plt and dt_tlsdesc_got.
* elf64-x86-64.c (elf_x86_64_finish_dynamic_sections): Updated.
* elfnn-aarch64.c (elf_aarch64_link_hash_table): Remove
tlsdesc_plt and dt_tlsdesc_got.
(elfNN_aarch64_allocate_dynrelocs): Updated.
(elfNN_aarch64_finish_dynamic_sections): Likewise.
(elfNN_aarch64_size_dynamic_sections): Updated. Clear
root.tlsdesc_plt for DF_BIND_NOW. Don't check DF_BIND_NOW
twice.
* elfxx-x86.c (elf_x86_allocate_dynrelocs): Updated.
(_bfd_x86_elf_size_dynamic_sections): Likewise.
(_bfd_x86_elf_finish_dynamic_sections): Likewise.
* elfxx-x86.h (elf_x86_link_hash_table): Remove tlsdesc_plt and
tlsdesc_got.
