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.
Introduced here: http://svnweb.freebsd.org/changeset/base/275153
