Code correction and added that we should make sure the process is alive and stopped.

Code correction:
```
lldb::SBError
SBProcess::SaveCore(const char *file_name)
{
lldb::SBError error;
if (process_sp)
{
Mutex::Locker api_locker (process_sp->GetTarget().GetAPIMutex());
FileSpec core_file(file_name, false);
error.ref() = PluginManager::SaveCore(process_sp, core_file);
}
else
error.SetErrorString ("SBProcess is invalid");
return error;
}
```
We might also want to check to make sure the process is alive (the "save-core" command makes sure the process has been launched) and we should also make sure it does the right thing if the process is running (stop the process, make a core file, then resume if the process was running, or just fail if the process is running).
