Replace the usage of the "instanceof" operator by a catch block.

Code Path:server/src/main/java/org/apache/iotdb/db/mpp/plan/analyze/AnalyzeVisitor.java

Multiple catch blocks of the appropriate type should be used instead of catching a general exception, and then testing on the type.

Start in server/src/main/java/org/apache/iotdb/db/mpp/plan/analyze/AnalyzeVisitor.java and inspect the general catch blocks that test exception types with instanceof. Replace that pattern with separate catches for the appropriate exception types, then verify the server's existing tests still pass.
