I added an rt.sections_ldc module that is just based on what we 
had before (i.e. reads the _Dmodule_ref chain). Entirely untested 
so far, there are probably big issues with it still (it might not 
even compile on non-Linux systems).

Next step would be to get the DMD testsuite to pass. I'm using a 
DMD-built d_do_test right now, as I think d_do_test is still 
miscompiled.
