x86: Add _bfd_x86_elf_link_hash_table_create

Share _bfd_x86_elf_link_hash_table_create in elf32-i386.c and
elf64-x86-64.c by:

1. Replace elf_i386_lazy_plt_layout, elf_i386_non_lazy_plt_layout,
elf_i386_plt_layout, elf_x86_64_lazy_plt_layout,
elf_x86_64_non_lazy_plt_layout and elf_x86_64_plt_layout with
elf_x86_lazy_plt_layout, elf_x86_non_lazy_plt_layout and
elf_x86_plt_layout.
2. Move plt, lazy_plt, non_lazy_plt, srelplt2 and next_tls_desc_index
from elf_i386_link_hash_table to elf_x86_link_hash_table.
3. Remove elf_i386_link_hash_table and elf_x86_64_link_hash_table.
