I committed as is because emit-rtl.h uses enum memmodel so all files that 
includes it must be updated. This gets worse because tm.h uses emit-rtl.h so all 
target needs to be updated as well. The diff was becoming big so I decided to 
keep it separate. I'll post the patch once it's complete and have gone through a 
few bootstrap.
