plt_tlsdesc_got2_offset, plt_tlsdesc_got1_insn_end and

x86-64: Add TLSDESC fields to elf_x86_lazy_plt_layout
ENDBR64 is added to the special TLSDESC entry, which is similar to the
PLT0 entry, in the x86-64 lazy procedure linkage table to support Intel
CET. The NaCl PLT is different from the normal PLT. This patch adds
plt_tlsdesc_entry, plt_tlsdesc_entry_size, plt_tlsdesc_got1_offset,
plt_tlsdesc_got2_offset, plt_tlsdesc_got1_insn_end and
plt_tlsdesc_got2_insn_end to elf_x86_lazy_plt_layout to support both
normal and NaCl TLSDESC entries. This fixed

x86-64: Add TLSDESC fields to elf_x86_lazy_plt_layout
ENDBR64 is added to the special TLSDESC entry, which is similar to the
PLT0 entry, in the x86-64 lazy procedure linkage table to support Intel
CET. The NaCl PLT is different from the normal PLT. This patch adds
plt_tlsdesc_entry, plt_tlsdesc_entry_size, plt_tlsdesc_got1_offset,
plt_tlsdesc_got2_offset, plt_tlsdesc_got1_insn_end and
plt_tlsdesc_got2_insn_end to elf_x86_lazy_plt_layout to support both
normal and NaCl TLSDESC entries. This fixed
FAIL: TLS descriptor -fpic -shared transitions

x86-64: Add TLSDESC fields to elf_x86_lazy_plt_layout
ENDBR64 is added to the special TLSDESC entry, which is similar to the
PLT0 entry, in the x86-64 lazy procedure linkage table to support Intel
CET. The NaCl PLT is different from the normal PLT. This patch adds
plt_tlsdesc_entry, plt_tlsdesc_entry_size, plt_tlsdesc_got1_offset,
plt_tlsdesc_got2_offset, plt_tlsdesc_got1_insn_end and
plt_tlsdesc_got2_insn_end to elf_x86_lazy_plt_layout to support both
normal and NaCl TLSDESC entries. This fixed
FAIL: TLS descriptor -fpic -shared transitions

x86: Add _bfd_x86_elf_size_dynamic_sections
elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are
very similar, except for the followings:
1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH.
elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since
GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE
for both i386 and x86-64.
2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only
if target_id == X86_64_ELF_DATA.
3. x86-64 has
if (s != htab->elf.srelplt)
s->reloc_count = 0;
and i386 has
s->reloc_count = 0;
i386 did have
if (s != htab->srelplt)
s->reloc_count = 0;

x86: Add _bfd_x86_elf_size_dynamic_sections
elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are
very similar, except for the followings:
1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH.
elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since
GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE
for both i386 and x86-64.
2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only
if target_id == X86_64_ELF_DATA.
3. x86-64 has
if (s != htab->elf.srelplt)
s->reloc_count = 0;
and i386 has
s->reloc_count = 0;
i386 did have
if (s != htab->srelplt)
s->reloc_count = 0;

changed it back to use reloc_count again. So it is correct to use
if (s != htab->elf.srelplt)
s->reloc_count = 0;
for both i386 and x86-64 now.
4. i386 and x86-64 use different DT_XXXs. They are handled by adding
them to elf_x86_link_hash_table.
With these changes, we can share _bfd_x86_elf_size_dynamic_sections in

x86: Add _bfd_x86_elf_size_dynamic_sections
elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are
very similar, except for the followings:
1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH.
elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since
GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE
for both i386 and x86-64.
2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only
if target_id == X86_64_ELF_DATA.
3. x86-64 has
if (s != htab->elf.srelplt)
s->reloc_count = 0;
and i386 has
s->reloc_count = 0;
i386 did have
if (s != htab->srelplt)
s->reloc_count = 0;
in the original commit:

Author: Alexandre Oliva <aoliva@redhat.com>

But it was removed by
commit 5ae0bfb60a576344d7f701605346282c1144499e

changed it back to use reloc_count again. So it is correct to use
if (s != htab->elf.srelplt)
s->reloc_count = 0;
for both i386 and x86-64 now.
4. i386 and x86-64 use different DT_XXXs. They are handled by adding
them to elf_x86_link_hash_table.

Remove bfd stub function casts.
This patch defines a bunch of new functions to use in the BFD target
structs rather than casting bfd_false or bfd_true and similar stub
functions. I've also renamed the stub functions to reflect their
parameters and put "error" in the name if they set bfd_error. The
latter change is important since there were quite a few uses of
bfd_false where setting bfd_error was inappropriate, for example in
elf_backend_allow_non_load_phdr and is_target_special_symbol.
