It is of course possible to use dmds backend but not very 
desirable, dmds backend works on an expression-tree, which would 
be expensive to build from the linear IR newCTFE uses.
Dmds backend is also very hard to debug for anyone who is not 
Walter.

CTFE is the common case will be fastest if executed without any 
optimizer interfering.
modern x86 chips done a very fine job indeed executing crappy 
code fast.
Therefore making it possible to get away with very simple and 
fast codegen.
(Where fast means code-generation speed rather then code 
execution speed).
