[GPOS] Fix mark-to-mark positioning when one of the marks is a ligature
...
This commit: a3313e5400
broke MarkMarkPos
when one of the marks itself is a ligature. That regressed 26 Tibetan
tests (up from zero!). Fix that. Tibetan back to zero.

[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.

This was broken as a result of 7b84c536c1

As Khaled reported, MarkMark positioning was broken with glyphs
resulting from a MultipleSubst. Fixed. Test with the ALLAH character
in Amiri.

I couldn't measure significant performance gains out of this; maybe

is simply not going to work. Oh well...
