Unrolled build for rust-lang#124463

Rollup merge of rust-lang#124463 - gurry:rename-func, r=TaKO8Ki

Rename `inhibit_union_abi_opt()` to `inhibits_union_abi_opt()`

`inihibit` seems to suggest that this function will inhibit optimizations whereas `inhibits` correctly indicates that it will merely _check_ that. With `inhibits` if conditions read more naturally e.g.:

```rust
if repr.inhibits_union_abi_opt() {
}
```
