You may be interested in watching 
http://dconf.org/2014/talks/franklin.html and reading 
https://www.packtpub.com/application-development/d-cookbook - 
both explain in details what was necessary to create a minimal 
runtime for barebone binary. It is not a fully-featured runtime 
though so actual answer may depend on your goals - you don't need 
to implement language features you are not going to use.
