Bug 764192 was pretty successful.  Even if it didn't find bug 709860, it immediately pointed us to a double-free.

There are some additional assertions in jemalloc which I didn't enable because they're not related to bug 709860.  But given how useful the assertions we've turned on have been, I think we might as well enable some more.  I doubt there will be any measurable performance implications here.

MOZ_TEMP_INVESTIGATION is temporary, but I'm thinking now that MOZ_JEMALLOC_HARD_ASSERTS should not be.
