6c09325838 C/C++ Overlay: Preserve entities that have at least one location in an unchanged file 
Previously, an entity would be discarded if it had any location in a changed
file. This caused issues for entities with multiple declaration entries, such
as extern variables declared in one file and defined in another.

For example, given:
  // a.c (changed)       // b.c (unchanged)
  extern int x;          int x;

The variable `x` should be preserved because it has a location in the
unchanged file b.c, even though it also has a location in the changed file a.c.

fe3f90e041 C++: Make getExpandedArgument more robust 
This make the predicate give back sensible results on (upgraded) databases
where we do not have expanded arguments, and avoid having to write case
distinctions in places where we would want to use `getExpandedArgument`.
