Is it acceptable to not parse unittest blocks when unittests are disabled ?

I wonder if `dmd -o-` should continue to parse everything (possibly 
including unittests, which it currently doesn't do) rather than parse 
lazily. Though it would benefit from a speed increase, it's used to syntax 
check and would be more useful if it actually does parse everything.
