06b8f74644 C#: Avoid combinatorial explosion in structural comparison library 
In cases where the target of a call/access has multiple values (which is a DB
inconsistency), the GVN construction underlying the structural comparision library
may run into a combinatorial explosion. This change excludes such expressions from
the GVN construction.
