I think the only changes (as opposed to additions) were to
main.cpp and to how it translates D type to llvm types (making it
somewhat aware of addrspaces) and possibly some logging suff to
figure out what it does. I'll have to run clang-format on it at
some point though.
There's a lot of semi-duplicate code though, I copied most of the
declaration and statement codegen stuff, and got rid of all the
stuff I wouldn't use, e.g. classes exceptions and whatnot.
