New Revision: 216606

URL: http://llvm.org/viewvc/llvm-project?rev=216606&view=rev
Log:
Update LLDB to use LLVM's DynamicLibrary.

LLDB had implemented its own DynamicLibrary class for plugin
support.  LLVM has an equivalent mechanism, so this patch deletes
the duplicated code in LLDB and updates LLDB to reference the
mechanism provided by LLVM.
