  -----------
  [SLP]Add an  extra check for select minmax reduction to avoid crash.

Need to check if the reduction is still (not)cmp-select pattern min/max
reduction to avoid compiler crash during building list of reduction
operations. cmp-sel pattern provides 2 reduction operations, while
intrinsics - just one.
