[LoopOptimizer][Fix]PR32859, PR24738
The Loop vectorizer pass introduced undef value while it is fixing output of LCSSA form.
Here it is:
before: %e.0.ph = phi i32 [ 0, %for.inc.2.i ]
after: %e.0.ph = phi i32 [ 0, %for.inc.2.i ], [ undef, %middle.block ]
and after this change we have:
%e.0.ph = phi i32 [ 0, %for.inc.2.i ]
%e.0.ph = phi i32 [ 0, %for.inc.2.i ], [ 0, %middle.block ]
