RE: [eigen] operator== (and probably others) for 0-sized Eigen-types

Hi Gael,

I tried your back port to 3.2 and it fixes the problem nicely. Now zero-sized vectors work as
expected in my tests.

Thanks Gael and Christoph!

Best regards

I also extended tests in zerosized.cpp. I did not find any test for boolean reductions alone, but I ran many tests which heavily depend on all()/any()..

If someone checked the commit feel free to back-port to other branches.
