For now, this is only for base_unittests. The plan is to enable it for all unit tests. This should finally fix mysterious problems cause by Singletons surviving after one test etc. This change also adapts LazyInstance so that it can be reused after being destroyed. It is used very frequently, for example each time a MessageLoop is used. It is also worth noting that we had some problems in the past related to the MessageLoop being destroyed and re-instantiated in the same test executable. This patch should also fix that.
