Don't think so. LDC is best at doing such transformation per my 
observations but it still major are for improvements in general.

I'd object against it general. Important trait of such builds is 
resulting code gen that matches original source code as much as 
possible. Mass inlining will kill it. But I don't see why you use 
"debug" and "non-optimised" as synonyms here. For example, in DMD 
"-release" vs "-debug" are orthogonal to "-O". I see no problems 
with doing optimised debug build.
