[GSUB/GPOS] Add get_coverage() and use it to speed up main loop
...
And use it to speed up the hotspot by checking coverage directly in
the main loop, not 10 functions deep in.
Gives me a solid 20% boost with Indic test suite. Less so for less
lookup-intensive scenarios.
Remove the "fast_path" hack from before.

I couldn't measure significant performance gains out of this; maybe
about 5% (with one million Malayalam strings). Still, not bad.
But reminds me that optimizing this codebase without profiling first
is simply not going to work. Oh well...
