Optimize harfbuzz big integer conversions
...
Profiling showed that type conversions were adding considerable cycles in time
spent doing text shaping.
The idea is to optimize it using native processor instructions to help Blink
layout performance.
Doing further investigation revelead that compilers may not use the
proper instruction on ARM 32bits builds (i.e. REV16).
One way to insure that the generated ASM was ideal for both gcc/clang
was using __builtin_bswap16.
Added bonus is that we no longer need to test for CPU architecture.

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.

[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.
