/*
Perform a clone system call. clone is strange because it has
fork()-like return-twice semantics, so it needs special
handling here.
Upon entry, we have:
word (fn)(void*) in r3
void* child_stack in r4
word flags in r5
void* arg in r6
pid_t* child_tid in r7
pid_t* parent_tid in r8
void* ??? in r9
Note: r3 contains fn desc ptr, not fn ptr -- p_fn = p_fn_desc[0]
System call requires:
int $__NR_clone in r0 (sc number)
int flags in r3 (sc arg1)
void* child_stack in r4 (sc arg2)
pid_t* parent_tid in r5 (sc arg3)
?? child_tls in r6 (sc arg4)
pid_t* child_tid in r7 (sc arg5)
void* ??? in r8 (sc arg6)
Returns a ULong encoded as: top half is %cr following syscall,
low half is syscall return value (r3).
