Garret Rieger
2bd911b8b4 [subset] handle cmap4 overflows. 
If a cmap4 subtable overflows during serialization drop it and the corresponding EncodingRecord. Don't drop the corresponding cmap12 table if it would have otherwise been removed.

[subset] speedup cmap4 subsetting for large codepoint counts. (#3178) 
glyphIdArray generation implementation was O(n^2). Refactored to use a hashmap to reduce complexity. After the change subset time for a 22k codepoint subset went from 7s to 0.7s.

f2441a4b65 [subset] Remove retain all layout features flag. 
Instead use inverted sets to handle requesting all features. Modifies feature collection in subset plan to intersect the set of requested features against the features in the font. This prevents iterating a fully filled feature tag set.

c90678cbc5 [set] One more try to fix things 
That I don't let a "make check -j10" run finish before pushing things
out means either that we need to speed up our build / test process,
or I need a faster laptop...
