Garret Rieger 8658c257c4 [subset] In LigatureSubst subsetting, check if the ligature glyph is in glyphset. 
Otherwise coverage will not match the retained ligature sets.

Garret Rieger 663ecc01d8 [subset] don't free glyphs by range. 
The iterator in this loop is a map iterator so glyphs are not necessarily traveresed in order.

Garret Rieger 3d05b96181 [subset] track which glyphs have allocated memory so we can clean up correctly.

Garret Rieger 918193ebf9 [subset] fix a class of fuzzer timeouts caused by large shared coverage tables. 
More acurately estimates the op count for CoverageFormat2 tables as the population size instead of the size in bytes.

It's possible that length of all_points equals to 4 for non-empty
glyphs: a composite glyph which contains only one child glyph that is
empty.

Behdad Esfahbod 64fa5cd482 [GPOS] Fix assert fail introduced recently 
Was introduced in 8708b9e081.

If these lookups are recursed to from (Chain)Context out-of-order,
it was possible that last_base > buffer->idx, in which case we
were attaching marks to a base after them... and an assertion
was failing fortunately.
