I took Sebastiaan's thing from two years ago and applied it to 
new druntime here:

https://github.com/adamdruppe/dmd/tree/wasm


I haven't tried actually compiling it yet though, I've been 
pretty swamped with work lately. When the new ldc comes out, I'll 
get Sebastiaan's documentation together and give it a try.

WebAssembly is a kind of CPU and WASI is a kind of C library.

So it should be two separate versions kinda like how there's 
version(X86) and version(Windows) and version(CRuntime_Microsoft) 
all independent (though often used together you don't have to).
