information associated with NameId from the `name` table and that should be
done separately.

[sanitize] Reorder condition to silence bogus gcc warning
...
Was givin a dozen of:
../../src/hb-machinery.hh: In member function ‘bool AAT::ankr::sanitize(hb_sanitize_context_t*) const’:
../../src/hb-machinery.hh:307:23: warning: missed loop optimization, the loop counter may overflow [-Wunsafe-loop-optimizations]
bool ok = --this->max_ops > 0 &&
~~~~~~~~~~~~~~~~~~~~~~
this->start <= p &&
~~~~~~~~~~~~~~~~~~~
p <= this->end &&
~~~~~~~~~~~~~~~^~
(unsigned int) (this->end - p) >= len;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I believe those are bogus, but this silences them and does not introduce
logic issues I believe.
