Log:
This patch extends the hack I added in
http://gcc.gnu.org/ml/gcc-patches/2012-01/msg01031.html to pacify the
garbage collector.

I have to keep using the same fake GC root because these trees are
added to structures that I can't seem to get properly annotated for
GC.  In particular, I'm having trouble with 'FILE' pointers.  I will
try to figure this out at some point, but we've got bigger issues to
address at the moment.

The specific problem this time was that bitsizetype was being
GC'd out while we were reading a PPH image.  This was causing
ICEs when we were trying to read many PPH images.
