New Analyzer: Synchronization in the constructor

[camrein]

Synchronization in the constructor is usually unnecessary since the constructor completes before any other operation on the object's members can be made (given that there are no data races in the invoking code). It may be necessary if the constructor creates a thread. However, this should be refactored to a factory method as PH_S007 suggests.

TBD: Check if static fields are accessed.
