Well from the point of view of the code you usually don't really 
care because it's just like passing a higher value of n to `-On`.

It's probably already implemented as an LDC specific __trait, but 
if it isn't it shouldn't be too hard to add to 
__traits(getTargetInfo) (the optimiser values that -mcpu=native 
sets probably will be made available through getTargetInfo at 
some point though).
