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.

[set] Optimize add_range()

Fix sign of shift operators

This one:
map->mask = (1 << (next_bit + bits_needed)) - (1 << next_bit);
before the fix, the shift was done as an int, causing overflow
if it ever got to 1 << 31. Sprinkle 'u's around.

I experimented with replacing use of hb_set_digest_t with this new

(like kern lookup in Roboto), but I only got 6% speendup in Roboto
and 4% in NotoNastaliqUrduDraft :(.
