The fuzzers have found the reloc special functions in coff-aarch64.c
All of them need a bfd_reloc_offset_in_range check before accessing
data + reloc_entry->address. This patch adds the missing checks and
sanity checks reloc offsets in coff_pe_aarch64_relocate_section too.
All of them also need changing to support objdump -W calls to
bfd_simple_get_relocated_section_contents. At least, secrel_reloc
needs the support, the others might not be present in dwarf debug
sections.
* coff-aarch64.c (coff_aarch64_rel21_reloc): Range check
reloc offset. Support final-linking.
(coff_aarch64_po12l_reloc): Likewise.
(coff_aarch64_addr32nb_reloc): Likewise.
(coff_aarch64_secrel_reloc): Likewise.
(coff_pe_aarch64_relocate_section): Range check reloc offset.
