  Log Message:
  -----------
  Revert "[SLP] allow matching integer min/max intrinsics as reduction ops"

This reverts commit 3c8473ba534daa3 and includes test diffs to
maintain testing status.

There's at least 1 place that was not updated with 7202f47508 ,
so we can crash mismatching select and intrinsics as shown in
PR49730.
