<pre>We should build an ObjectLinkingLayer plugin to enable debugging of JIT'd code.
MCJIT / RuntimeDyld already has GDBRegistrationListener for this purpose. We
may want to look at whether we can re-use the GDB registration protocol for
this. See:
<a href="http://llvm.org/PR1129">http://llvm.org/PR1129</a>, <a href="http://llvm.org/PR17628">http://llvm.org/PR17628</a>, and
<a href="https://sourceware.org/gdb/current/onlinedocs/gdb/JIT-Interface.html">https://sourceware.org/gdb/current/onlinedocs/gdb/JIT-Interface.html</a>.
If we go this route then ideally the plugin will synthesize a new object with
the necessary section/segment load commands, nlist entries, and dwarf sections,
but without the dead weight of all the actual code and data.</pre>
