Behdad Esfahbod ec925ece05 [khmer] Reinstate a pause after basic features 
This was removed as part of 044d7a06db,
which caused the regression.  Just adding a pause fixes the shaping.
Debugged by just tracing the good/bad shaping and observing the
lookup orders intermingling in the bad shaping.

Test:

Qunxin Liu 7cb002cb58 [subset] bug fix in prune_langsys 
we should not cache visited langsys cause 2 different Record<Langsys>
could have different Tag while pointing to the same Langsys, a langsys
is redundant in Record<Langsys> A does not mean it's redundant in Record
B. Same thing for visited_script.
Also adding the number of features in the LangSys's feature list to the
visited langsys count so it's more accurate.
Plus some improvement in langsys compare()

Merge pull request #3410 from harfbuzz/boring-expansion 
[Boring Expansion] >64k loca & hmtx tables

This does two things:

The num-glyphs reported by the face now is the maximum reported by the maxp and that deduced from the length of the loca table; I think this is the right thing to do anyway; According to OpenType such loca tables are invalid.

The interpretation hmtx tables that have excessive bytes at the end, again, invalid according to OpenType, has changed. Previously we were interpreting those excessive bytes as extra lsb values. Now we interpret them as extra advance values, the last of which is repeated for all missing glyphs. Again, these are tables that are invalid according to OpenType, and the advances are for glyph indices beyond maxp table's num-glyphs.

The combined effect is that the font can have shapes and advances for gid's beyond the maxp limit of 64k. In fact, maxp table becomes optional.
