Ah, I must have overlooked it in the merge.
Out of curiosity, what is the common case here? If the profiler is
usually turned on, this might be faster:
Cmp(w10, 0);
Csel(x3, function_address, Operand(thunk_ref), eq);
It's smaller by one instruction (and doesn't branch), but if the
profiler is disabled we waste a few cycles loading the
ExternalReference.
