Briefly, like what?

Yesterday and today I've been playing with a re-organization
of ggc-page.c such that we no longer segregate object sizes
into different pages.  

I've only had a chance to do limited performace testing on 
the thing so far (which is why I havn't posted it).  Despite
the theoretical higher overhead of the metadata, core sizes
do appear to be smaller.  Runtime performance is a little 
worse still; I'm hoping that's fixable.
