Right now compacting GC does a couple of things to help show up bugs:
 - in 64 bit debug builds, a compacting GC relocates everything
 - in debug builds relocated arenas are mprotected and not released until the next GC

We should restrict this zealousness to when zeal mode collections.  We already have a build where the shell tests are run in CGC zeal mode, and I think it makes sense if possible to add a browser build too.
