Switch from a 128+64 hierarchy, to 32+32. New page size is 1024. This should make set iteration faster, without affecting other op performances much.

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. Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=794896

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.

It's as good as it gets, and seems to be on par with previous set implementation in my benchmark. Would be great if someone can double-check my bitops.

With new set implementation, this became really costy. Optimize it. There's more to be done, but this shaves off most of the fat. Part of fixing https://bugs.chromium.org/p/chromium/issues/detail?id=782220
