[ot] Fix VariationStore evaluation algorithm
...
Ouch! Missing coords should still be evaluated as coord=0, which
most of the time results in a factor of 0. We were skipping these,
which was equivalent to a factor of 1.

Improve CGJ skipping logic
...
Previously we made CGJ unskippable. Now, if CGJ did NOT prevent
any reordering, allow skipping over it. To make this work we
had to make changes to the Arabic mark reordering algorithm
implementation to renumber moved MCM marks. See comments.

atomics: Favor compiler primitives over macOS APIs. ( #676 )
...
In macOS 10.12, the `OSMemoryBarrier` and related APIs were deprecated
in favor of using `std::atomic`. On the way to supporting `std::atomic`,
we can favor using the "Intel primitives" which are also available on
macOS.

[collect_glyphs] Bail if input data looks like garbage
...
Specificaly, when a range or sorted array has unexpected order, we take that as
font data being garbage and bail out. This fixes significant slowdown on a bad
version of Chandas font which has a 600KB GPOS with garbage inside.
Later on, I like to add a maximum-work counter for collect_glyphs to protect
against malicious fonts as well.

Not optimized to use sortedness yet. Also start putting in place infra
to faster reject bad data.
A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS,
mostly junk. That is causing 48 million of set->add() calls in
collect_glyphs(), which is insane.
In the upcoming commits, I'll be speeding that up by optimizing
add_sorted_array(), while also reducing work by rejecting out-of-sort
arrays quickly and propagate the rejection.
