[GSUB/GPOS] Use Coverage digests as gatekeeper
...
Gives me a good 10% speedup for the Devanagari test case. Less so
for less lookup-intensive tests.
For the Devanagari test case, the false positive rate of the GSUB digest
is 4%.

[GPOS] Adjust mark advance-width zeroing logic
...
If there is no GPOS, zero mark advances.
If there *is* GPOS and the shaper requests so, zero mark advances for
attached marks.
Fixes regression with Tibetan, where the font has GPOS, and marks a
glyph as mark where it shouldn't get zero advance.

[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.
