Since dmd is only targeting x86/x86_64 there is really just one 
arch to support for now.
All the others can fallback to either the interpreter or 
generated c code compiled into a shared lib :)

newCTFE already provides a very low-level IR that should be 
trivially translatable to machine -code. (famous last words :o) )
