0.9.5.52:
        More merging. Make non-purified cores suck less.

        * Do a non-conservative GC when saving a core without purifying.
        * Save critical bits of the page table in the core, to allow
          picking up the core without walking through the whole core.
        * The dynamic section of a core is picked up into a special
          non-collected generation (currently called "pseudo static"
          in the source, but I'm not attached to that name).
        * #ifdef out some fixup code that's not needed on x86-64.
        * Refactor save.c a bit.
