      Normalize bounds fully when checking defaulted types
      
      When checking that the default type for `<T as X>::Y` is valid in this example:
      
      ```
      trait X { type Y: PartialEq<<Self as X>::Y> }
      impl X for T { default type Y = S; }
      ```
      
      We will have to prove the bound `S: PartialEq<<T as X>::Y>`. In this case
      we want `<T as X>::Y` to normalize to `S`. This is valid because we are
      checking the default value specifically here. Add `<T as X>::Y = S` to the
      ParamEnv for normalization _of the bound we are checking_ only.
      
      Fixes #73818.
      
      ---
      
      I noticed that adding this to the env for bounds checking didn't break any tests. Not sure if this is because we can't rely on it to prove anything, or because of missing test coverage.

      Fix panic message when `RangeFrom` index is out of bounds
      
      Before, the `Range` method was called with `end = slice.len()`. Unfortunately, because `Range::index` first checks the order of the indices (start has to be smaller than end), an out of bounds index leads to `core::slice::slice_index_order_fail` being called. This prints the message 'slice index starts at 27 but ends at 10', which is worse than 'index 27 out of range for slice of length 10'. This is not only useful to normal users reading panic messages, but also for people inspecting assembly and being confused by `slice_index_order_fail` calls.
      
      You can see the produced assembly [here](https://rust.godbolt.org/z/GzMGWf) and try on Playground [here](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=aada5996b2f3848075a6d02cf4055743). (By the way. this is only about which panic function is called; I'm pretty sure it does not improve anything about performance).
