Dinar Temirbulatov 31d4c97506 [LoopVectorize] LLVM fails to vectorise loops with multi-bool varables (#89226) ...

This change allows to consider compare instructions in the loop with
multiple use inside the loop and outside.

This change allows to vectorise this loop:
int foo(float* a, int n) {
  _Bool any = 0;
  _Bool all = 1;
  for (int i = 0; i < n; i++) {
    if (a[i] < 0.0f) {
      any = 1;
    } else {
      all = 0;
    }
  }
  return all ? 1 : any ? 2 : 3;
}
