    A llvm/test/Transforms/SLPVectorizer/X86/reorder-possible-strided-node.ll

  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.
