Add more detail to type inference error

When encountering code where type inference fails, add more actionable
information:

```
fn main() {
    let foo = Vec::new();
}
```

```
error[E0282]: type annotations needed in `std::vec::Vec<T>`
  --> $DIR/vector-no-ann.rs:2:16

LL |     let foo = Vec::new();
   |         ---   ^^^^^^^^ cannot infer type for `T` in `std::vec::Vec<T>`
   |         |
   |         consider giving `foo` a type
```

Fix #25633.

Fix lines highlighting in rustdoc source view

Fixes #60948.

This PR fixes how we handle the lines highlighting from the URL (so in "/doc/src/alloc/string.rs.html#285-283", the "285-283" part). We got a hard limit on 50000, for some unknown and lost reasons which was used in case only one line is selected.

4c7bb8b0d9 Auto merge of #61276 - eddyb:kill-res-upvar, r=petrochenkov 
rustc: remove Res::Upvar.

By keeping track of the current "`body_owner`" (the `DefId` of the current fn/closure/const/etc.) in several passes, `Res::Upvar` and `hir::Upvar` don't need to contain contextual information about the closure.

By leveraging [`indexmap`](https://docs.rs/indexmap), the list of upvars for a given closure can now also be queried, to check whether a local variable is a closure capture, and so `Res::Upvar` can be merged with `Res::Local`.

And finally, the `tcx.upvars(...)` query now collects upvars from HIR, without relying on `rustc_resolve`.

538e17a3fd Auto merge of #61384 - varkor:fmin-fmax-llvm-opt, r=alexcrichton 
Update LLVM to include fmin/fmax optimisations

This will enable us to test if the optimisation issues mentioned in https://github.com/rust-lang/rust/issues/18384 really are fixed. Unfortunately, using the intrinsics immediately is problematic due to the libcore/libstd split (see https://github.com/rust-lang/rust/issues/50145).
