Subject: [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).

Fixes: <rdar://problem/10892489>
