Behdad Esfahbod a9fe787a11 [sanitizer] Add reset_object(), make set_object() do bounds-check
Affects morx/kerx run-time only currently.  Will adjust their sanitize next.

Behdad Esfahbod 3b9fd176e8 Disallow taking Null() of unbounded structs
Not sure I've marked all such structs.  To be done as we discover.

Behdad Esfahbod d062ad10de Fix bots happy again, hopefully
So, our fallback static_assert cannot be had more than once per line
of source.

Behdad Esfahbod dc4225ccd1 Don't retry creating again and again in lazy_loader if create failed
Still does that if get_null() returns nullptr.  Our shaper data objects
are like that.  Shrug.

Behdad Esfahbod 35d410f2ba Remove ASSERT_POD
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything.  Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.

Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.

There's a few more but those are functions that need to be filled in.

Maybe this is a lost battle...

Behdad Esfahbod e9f9c0d81c [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.
