  Log Message:
  -----------
  [modules] Update visibility for merged ObjCInterfaceDecl definitions.

We keep using the first encountered definition and need to take into
account visibility from subsequent definitions. For example, if the
first definition is hidden and the second is visible, we need to make
the first one visible too.
