[analyzer] fix regression in analyzer of NOT actually aborting on Stmts it doesn't understand. We registered

as aborted, but didn't treat such cases as sinks in the ExplodedGraph.

Along the way, add basic support for CXXCatchStmt, expanding the set of code we actually analyze (hopefully correctly).
