Don't create a new locale on every to_string() call.

Creating locales is surprisingly expensive. We have an application where we - especially during tests - write large amounts of Thrift dumps to disk, and is this application we currently spend around 17% of total CPU time in std::locale's constructor. With this change, it's basically down to zero.
