  Log Message:
  -----------
  [SLP]Do not try to reorder possible strided nodes.

Reordering of possible strided nodes in bottom-to-top order requires
top-to-bottom reordering of the operands of such nodes, which is not
supported. Need to disable reordering of strided operands to avoid
compiler crashes.
