439ff69d90 Add a way to get shorter spans until char for pointing at defs
```rust
error[E0072]: recursive type `X` has infinite size
  --> file.rs:10:1
   |
10 | struct X {
   | ^^^^^^^^ recursive type has infinite size
   |
   = help: insert indirection (e.g., a `Box`, `Rc`, or `&`) at some point to make `X` representable
```

vs

```rust
error[E0072]: recursive type `X` has infinite size
  --> file.rs:10:1
   |
10 |   struct X {
   |  _^ starting here...
11 | |     x: X,
12 | | }

fb99d87c46 update UI test
We no longer give suggestions; this is presumably related to the changes
I made in coercion. However, those suggestions appear to be wrong
anyhow!

78ae8feebb Improve wording and spans for unexpected token
* Point at where the token was expected instead of the last token
  successfuly parsed.
* Only show `unexpected token` if the next char and the unexpected token
  don't have the same span.
* Change some cfail and pfail tests to ui test.
* Don't show all possible tokens in span label if they are more than 6.

8d1c5700f0 Rollup merge of #40369 - petrochenkov:segspan, r=eddyb
Give spans to individual path segments in AST

And use these spans in path resolution diagnostics.

The spans are spans of identifiers in segments, not whole segments. I'm not sure what spans are more useful in general, but identifier spans are a better fit for resolve errors.

HIR still doesn't have spans.

Fixes https://github.com/rust-lang/rust/pull/38927#discussion_r95336667 https://github.com/rust-lang/rust/pull/38890#issuecomment-271731008
