Long story short, we're currently working on a self-hosted implementation of the compiler and what people are using now is the old C++ implementation. As soon as the new compiler is feature-complete enough, we'll start shipping it and we expect much better compilation speeds, which will be even greater speed for debug builds once the native (i.e., non-llvm) backends catch up as well.
