Fix save-analysis generation crash with invalid tuple access

Reproduction:

```rust
fn invalid_tuple_struct_accessing() {
    bar.0;
}
```
```
error[E0425]: cannot find value `bar` in this scope
 --> test.rs:2:5
  |
2 |     bar.0;
  |     ^^^ not found in this scope

error[E0601]: main function not found

error: internal compiler error: librustc_save_analysis/dump_visitor.rs:1678: Expected struct or tuple type, found TyError
 --> test.rs:2:5
  |
2 |     bar.0;
  |     ^^^^^

thread 'rustc' panicked at 'Box<Any>', librustc_errors/lib.rs:482:9
note: Run with `RUST_BACKTRACE=1` for a backtrace.
```

This should fix a crash in RLS when editing such code. cc @nrc

Rollup merge of #47463 - bluss:fused-iterator, r=alexcrichton 
Stabilize FusedIterator

FusedIterator is a marker trait that promises that the implementing
iterator continues to return `None` from `.next()` once it has returned
`None` once (and/or `.next_back()`, if implemented).

The effects of FusedIterator are already widely available through
`.fuse()`, but with stable `FusedIterator`, stable Rust users can
implement this trait for their iterators when appropriate.

Closes #35602

Rollup merge of #48432 - flip1995:lit_diag, r=oli-obk 
Suggest type for overflowing bin/hex-literals

Fixes #48073

For hexadecimal and binary literals, which overflow, it gives an additional note to the warning message, like in this [comment](https://github.com/rust-lang/rust/issues/48073#issuecomment-365370113).

Additionally it will suggest a type (`X < Y`):
- `iX`: if literal fits in `uX` => `uX`, else => `iY`
- `-iX` => `iY`
- `uX` => `uY`

Exceptions: `isize`, `usize`. I don't think you can make a good suggestion here. The programmer has to figure it out on it's own in this case.

259e4a6784 Auto merge of #48592 - spastorino:borrowed_value_error, r=nikomatsakis 
[NLL] Avoid borrowed value must be valid for lifetime '_#2r..." in errors

Closes #48428

- [x] If NLL is enabled, [do not invoke `note_and_explain_region`](https://github.com/rust-lang/rust/issues/48428#issuecomment-367691123)
- [x] Modify `-Zdump-nll-cause` to not print [the overwhelming debug output here](https://github.com/rust-lang/rust/blob/master/src/librustc_mir/borrow_check/nll/region_infer/mod.rs#L1288-L1299). This way we should I believe at least get nice-ish output for [our original example](https://github.com/rust-lang/rust/issues/48428#issue-299364536).
- [x] Extend `explain_why_borrow_contains_point` to also work for "universal lifetimes" like the `'a` in [the example at the end of this comment](https://github.com/rust-lang/rust/issues/48428#issuecomment-367691123).
- [ ] Figure out how to enable causal information all the time (but that is https://github.com/rust-lang/rust/issues/46590).
