remove value buddies after setting sites to junction sites, not after populating junction sites
...
This mirrors how snapshots are captured and restored for branch events.
Also, switch back to resolving junction sites before capturing fork
snapshots so we capture the true state of each value immediately before
the branch.

remove the libstdc++ dependency once and for all
...
The trick is to make all destructors non-virtual. This is safe because
we never use the delete operator, which is the only case where virtual
destructors are relevant. This is a better solution than implementing
our own delete operator, because we want libraries loaded at runtime to
use the libstdc++ version, not ours.
