Usually sharable strings are automatically promoted to shared old space
and can be shared in-place.
There are currently two exceptions:
- When using a non-moving GC (e.g. minor MC)
- Strings in LO space
Account for these exceptions by copying strings to the respective shared
space when sharing them.
