[OT] Remove likely() from coverage check
Not that it matters, but because of the set-digest, this path
is not very likely() anymore.

[layout] Cache subtable coverages in hb_map_t
Proof-of-concept. Going to revert. Memory consumption is more

Perhaps if we could add logic to choose which subtables to
cache, this might be a useful approach.
