Title: patmat tweaks: compiler performance, better error on unsupported pattern

- move a catch of a StackOverflowError up the call stack since @gkossakowski diagnosed it to be killing compiler performance
- Roland reported hitting the unsupported pattern branch in translatePattern in akka code, so providing some diagnostics and a nicer error message to figure out what's going on
