unittests are really part of the build, not a special run

tl: dr: please, no

We have put quite some effort into fighting default DMD behaviour 
of -unittest simply adding to main function and not replacing it. 
Initially many applications did run tests on startup because DMD 
suggested it is a good idea - some rather bad practical 
experience has shown this was a rather bad suggestion. Accidental 
tests that start doing I/O on productions servers, considerably 
increased restart times for services - that kind of issues.

And if you suggest to build both test and normal build as part of 
single compiler call (building test version silently in the 
background) this is also very confusing addition hardly worth its 

Just tweak your editors if that is truly important. It is not 
like being able to click some fancy lines in GUI makes critical 
usability addition to testing.
