Port to aarch64 (ARM 8).
Continuations don't work yet.
* gc.c (STACK_TOP_EXTRA_WORDS): New macro.
(mark): On aarch64, we must include four words above
the stack top. Some live root pointers sometimes
hide there which are not in any of the callee-saved register
that end up in the machine context via jmp_save.
* jmp.S (jmp_save, jmp_restore): Implement for aarch64.
