I can't wait to use foreach internally!  No more manual for loops!

I've started on the glue layer, and most of that should be done soon, but 
the backend brings a bunch of complications:
- The code style is nothing like the frontend
- It makes heavy use of the preprocessor
- We don't have a good way of testing it, which makes refactoring risky

My current plan is to create a nice text form of the backend's IR, then 
convert DMC's test suite to this format, with before and after snapshots.  I 
can then feed these tests through DMD's backend (no need for a C++ frontend 
any more) to check for regressions, letting me start modernizing the code 
and converting it to D.

This is going to take a while.
