Available here[1][2], it can now build a simple add kernel for

A lot of things are still hardcoded and the optimisations need
to tuned a bit more but it works.
Any and all testing, feedback,bug reports and pull requests
welcome!
I'll be working on it the next two weeks, after which I go
back to uni and will have less time to work on it, so the more
feed back the better!

What did you have to modify in LDC? Was the change important?
I'm asking because the lesser the change the more likely it is
to be maintanable in the future and/or added to LDC as a proper
extension.
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.
