When you want to reload a memory operand into dp1L, you might need
a secondary reload, as in this example.  Likewise  for dp2L for
memory operands using dp2L.  Make sure this is reflected in
SECONDARY_RELOAD_CLASS.  (or SECONDARY_INPUT_RELOAD_CLASS &
SECONDARY_OUTPUT_RELOAD_CLASS if you need to make them different).
If you defined MEMORY_MOVE_COST, also make sure that you take
memory_move_secondary_cost into account.
