[subset-cff] Compact parsed strings if using accelerator
...
Saves 32% on SourceHanSans/10000 benchmark!
Also, use memcmp now for writing out strings since now that our
ops are not super short, that's faster.
This makes cff-japanese test takes super long though; that needs
inspection.

Instead run a closure on the retained charstrings and copy only the referenced subrs. This significantly speeds up cases with small character sets.

The charstring objects reference memory from the original face so we need to maintain a reference to prevent it from being destroyed.

[buffer-diff] Fix check for glyph flag equality
...
I'm not sure if the old behavior was intentional, but it was checking
that the glyph flags were a subset of the reference buffer's glyph
flags. I don't see why that is useful. Fix that.
Then make the buffer-verify code ignore flag differences when verifying
buffers, since our unsafe-to-concat flag at least, is conservative and
not guaranteed to be produced the same in fragments. See:
