  [SLP]Fix PR66176: SLP incorrectly reorders select operands.

On the very first iteration for the reductions, when trying to build
reduction for boolean logic operations, no need to compare LHS/RHS with
the Reduction(VectorizedTree), need to compare with actual parameters of
the reduction operations.
