Preserve ->move_dr behavior when adjusting epilogue info

When update_epilogue_loop_vinfo relates the shared loop DRs with
the epilogue stmts and infos it should not fiddle with how
pattern recognition applied move_dr.

* tree-vect-loop.cc (update_epilogue_loop_vinfo): A DRs
main stmt vinfo dr_aux should refer to a pattern stmt
which is how move_dr sets this up.  We shouldn't undo this.
