  Log Message:
  -----------
  [SLP]Do not try to use interleaved loads, if reordering is required

If the interleaved loads require reordering, better to avoid generate
load + shuffle sequence, which in this case cannot be recognized as
interleaved load. Also, it fixes the issue with the incorrect codegen.

Fixes #138923
