Actually upon a second look it has nothing to do with that, that get_loop_body
doesn't make much sense there anyways. I believe that should have just been
'loop' as slpeel_tree_duplicate_loop_to_edge_cfg creates a copy of LOOP from
LOOP if LOOP == SCALAR_LOOP.  The problem here lies with using SCALAR_LOOP for
an epilogue... not quite sure what is wrong though.

Confirmed. It seems get_loop_copy is returning NULL. I'm looking into it.
