VarC: cast ints (#3934) 
msvc is rightfully complaining that the types on the sides of
the ternary are not matching:

```
C:\pango\subprojects\harfbuzz\src\OT\glyf\VarCompositeGlyph.hh(317): error C2446: ':': no conversion from 'const OT::HBUINT16' to 'const OT::HBUINT8'

Garret Rieger 38a9628885 [subset] simplify handling of table subsetting depedencies. 
Allow the dependency checker to see all tables that will be subset. Use this to fix the HMTX/VMTX dep check against glyf. Don't delay hmtx/vmtx subsetting if no glyf table is present.
 2022-12-12 20:13:17 +00:00
Garret Rieger 0853e5d9d7 [subset] if table dependencies can't be resolved fail the subset. 
Avoids getting stuck in an infinite loop.

Behdad Esfahbod 2644540a74 [subset-cff] Compact parsed strings if using accelerator 
Saves 32% on SourceHanSans/10000 benchmark!

ops are not super short, that's faster.

This makes cff-japanese test takes super long though; that needs
inspection.
