Log:<br>
[SLP] Fix for PR31690: Allow using of extra values in horizontal<br>
reductions.<br>
<br>
Currently, LLVM supports vectorization of horizontal reduction<br>
instructions with initial value set to 0. Patch supports vectorization<br>
of reduction with non-zero initial values. Also, it supports a<br>
vectorization of instructions with some extra arguments, like:<br>
```<br>
float f(float x[], int a, int b) {<br>
float p = a % b;<br>
p += x[0] + 3;<br>
for (int i = 1; i < 32; i++)<br>
p += x[i];<br>
return p;<br>
}<br>
```<br>
Patch allows vectorization of this kind of horizontal reductions.<br>
