Instead of adding individual micro-optimisation features like 
this, I'd be more interested in the potential for profile-guided 
optimisation (which *ideally* can make these micro-optimisation 
decisions automatically). Since DMD already has some framework in 
place to support code profiling, I suspect this is at least a 
feasible enhancement.

On the other hand, it might not be worth trying to play catch-up 
with existing PGO features in GCC/LLVM. If you're using PGO, 
you're probably already using these other backends for their more 
advanced static optimisers.
