Revert "[vector] Optimize grow_vector() for size"
...
This reverts commit 1dd9396c7a
.

[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.
