JDK-8305185 - C2 failed "assert(false) failed: Can't determine return type."
Description
I added this assert before the bailout, because it probably hides bugs. Now we have failure reports with JDK-8305185.

It is difficult to reproduce, so I'd like to add some print statements to get at least a bit of info.
