Hi,
this patch adds the CONSTRUCTOR case discussed while back. Only empty

I tested that during bootstrap about 7500 matches are for empty ctors.
There are couple hundred for non-empty probably used on generic.

OK. It'd be useful to have a test which shows that matching these
results in some kind of difference we can see in the dump files.
