Add checks for the NT_ARM_SVE section in a core file.
The NT_ARM_SVE section is documented here:
https://github.com/torvalds/linux/blob/master/Documentation/arm64/sve.txt
* A NT_ARM_SVE note will be added to each coredump for each thread of the
dumped process. The contents will be equivalent to the data that would have
been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread
when the coredump was generated.
* elf.c (elfcore_grok_aarch_sve): New function.
(elfcore_grok_note): Check for Aarch64 SVE.
(elfcore_write_aarch_sve): New function.
(elfcore_write_register_note): Check for Aarch64 SVE.
* elf-bfd.h(elfcore_grok_aarch_sve): New declaration.
