These changes add support for build and target configurations in the compiler. Build and target configurations, combined with the use of #if/#else/#endif allow for conditional compilation within declaration and statement contexts. Build configurations can be passed into the compiler via the new '-D' flag, or set within the LangOptions class. Target configurations are implicit, and currently only "os" and "arch" are supported.
