I'm working on fixing everywhere that can introduce bitcasts between 
address spaces. You need this if you want objectsizes on multiple 
objects in different address spaces to coexist. Since these are compile 
time constants that just try to find object definitions and then 
disappear, it might work to addrspacecast everything to address space 0? 
I'm not 100% sure that would always be OK though.
