Sometimes, but not reliably. We delete out of scope watchpoints partly
by setting an appropriate breakpoint at the function return address,
and there is no equivalent exit address for nested scopes.
Another problem with watchpoints is that we don't support any kind of
location lists for local variables; that's a similar problem.
