Log:
  Pull in r216571 from upstream llvm trunk (by Zachary Turner):
  
    Fix some semantic usability issues with DynamicLibrary.
  
    This patch allows invalid DynamicLibrary instances to be
    constructed, and fixes the const-correctness of the isValid()
    method.
  
    No functional change.
  
  This is needed for supporting the upgrade to a newer LLDB snapshot.
