removed. Update after the changes to elf32_arm_link_hash_entry.

entries should live in .plt or .iplt. Check whether the .igot.plt
and .got entries can be combined. Use elf32_arm_allocate_plt_entry
to allocate .plt and .(i)got.plt entries. Detect which .got
entries will need R_ARM_IRELATIVE relocations and use
elf32_arm_allocate_irelocs to allocate them. Likewise other
non-.got dynamic relocations.
(elf32_arm_size_dynamic_sections): Allocate .iplt, .igot.plt
and dynamic relocations for local STT_GNU_IFUNC symbols.

section pointers intead of strcmp checks. Handle iplt and igotplt.
(elf32_arm_finish_dynamic_symbol): Use elf32_arm_populate_plt_entry
to fill in .plt, .got.plt and .rel(a).plt entries. Point
STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
resolve to it.
(elf32_arm_output_plt_map_1): New function, split out from
elf32_arm_output_plt_map. Handle .iplt entries. Use
elf32_arm_plt_needs_thumb_stub_p.
