This patch adds support for AArch64 to SystemSan. Even if builder support is not complete yet (#8164), it makes it easier to hack on this sanitizer locally.

This is not a big change:

  • PTRACE_GETREGS is not implemented for this architecture; it is replaced by PTRACE_GETREGSET.
  • Register names are behind a new macro, defined in arch.h.
