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.

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert()
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

This reverts commit 94bfea0ce6.
This reverts commit 4e62627831.

Behdad Esfahbod fda994e1d4 Use enum instead of "static const" in class scope
Technically, static const needs an out-of-class definition.  Eg:

Behdad Esfahbod e58b190292 [subset] De-templatize hb_subset_context_t
We're going to (finally) use virtual methods for hb_serialize_context_t
customization, so don't need to carry a Serializer template variable
around...  Simplifies code.
