Unrolled build for rust-lang#118035

Rollup merge of rust-lang#118035 - ouz-a:november_ice2, r=compiler-errors

Fix early param lifetimes in generic_const_exprs

In cases like below, we never actually be able to capture region name for two reasons, first `'static` becomes anonymous lifetime and second we never capture region if it doesn't have a name so this results in ICE.
```
struct DataWrapper<'static> {
    data: &'a [u8; Self::SIZE],
}

impl DataWrapper<'a> {
```

Fixes rust-lang#118021
