The global bitmap was being corrupted during garbage collection because
it was not marked in the GC roots.  I tried putting the bitmap on the
default bitmap obstack, but it gets swiped from under us all over the
compiler, thus not suitable for a persistent object.

The following patch marks the global bitmap as a root, and clears the
bitmaps when not needed.

OK for branch?

OK
