DDMD just went green on all platforms for the first time

This is a pretty big milestone for the project.  For the first time, an 
unpatched dmd can build ddmd, and that ddmd can build druntime and phobos 
and pass all the test suites.

Hopefully in the next couple of weeks the remaining minor issues will be 
fixed (eg makefile changes, ddmd runs out of memory compiling std.algorithm 
unittests on win64) and we can start adding ddmd to master alongside the C++ 
compiler.

A big thanks to Brad for upgrading the autotester, and to everyone who has 
helped fix bugs and get patches merged over the last couple of years.

Github shows 376 closed DDMD pull requests, which is about 8% of all dmd 
pull requests ever.
