performance-for-range-copy check.
Summary:
The upstream change r336737 make the check too smart to fix the case
where loop variable could be used as `const auto&`.
But for the case below, changing to `const auto _` will introduce
an unused complier warning.
```
for (auto _ : state) {
// no references for _.
}
```
This patch omit this case, and it is safe to do it as the case is very rare.
