As I was typing up a comment in phabricator about mach hazards clobber, I realized that it would make more sense to store the *.xdb files in obj-analyzed-{js,browser} rather than haz-{js,browser}. If you want a clean reanalysis, you need to blow away both the objdir and the xdb files. If you want an incremental reanalysis, you want to keep both. While in practice I have a tendency to delete the objdir and not the *.xdb files and then rebuild, I don't think it's actually helping me any. And it's the easiest way to get lots and lots of bogus "symbol has different type" warnings from sixgill.
