One of the links in the docs was being rendered as a literal open-bracket followed by a single quote, instead of being transformed into a link. Fix it to match the link earlier in the same paragraph.
This was essentially a "query" previously (with no key, just always run once when resolving the crate dependencies), and remains so, just now in a way that isn't on Session. This removes the need for the `Once` as well.
Similarly to the previous commit, there's no need for this to be in Session and have a Once around it.
In bootstrap, we set `RUSTC_INSTALL_BINDIR` to `config.bindir`, so rustdoc can find rustc relative to the toolchain sysroot. However, if a distro script like Fedora's `%configure` sets an absolute path, then rustdoc's `sysroot.join(bin_path)` ignores that sysroot altogether. That would be OK once the toolchain is actually installed, but it breaks the in-tree doc tests during the build, since `/usr/bin/rustc` is still the old version. So now we try to make `RUSTC_INSTALL_BINDIR` relative to the sysroot prefix in the first place.
This makes it easier to add new non-standard constructors, and this also ensures that we don't forget cases when adding a new constructor.
It counts as an extra constructor for types that are not allowed to be matched exhaustively.
The single dependency on queries (QueryName) can be fairly easily abstracted via a trait and this further decouples Session from librustc (the primary goal).
This helps decouple the lint system from needing the implicit TLS TyCtxt as well.

add Result::map_or
This PR adds this API to make it consistent with `Option::map_or`.
```rust
impl<T, E> Result<T, E> {
pub fn map_or<U, F: FnOnce(T) -> U>(self, default: U, f: F) -> U {
match self {
Ok(t) => f(t),
Err(_) => default,
}
}
}
```
This API is very small. We already has a similar API for `Option::map_or`.
Add a callback that allows compiler consumers to override queries. This pull request adds an additional callback that allows compiler consumers such as Prusti and MIRAI to override queries. My hope is that in this way it will be possible to get access to the internal compiler information (e.g. borrow checker) without major changes to the compiler. This pull request is work in progress because I am still testing if I can get the information which I need. cc @nikomatsakis r? @oli-obk
…ulacrum Use a relative bindir for rustdoc to find rustc In bootstrap, we set `RUSTC_INSTALL_BINDIR` to `config.bindir`, so rustdoc can find rustc relative to the toolchain sysroot. However, if a distro script like Fedora's `%configure` sets an absolute path, then rustdoc's `sysroot.join(bin_path)` ignores that sysroot altogether. That would be OK once the toolchain is actually installed, but it breaks the in-tree doc tests during the build, since `/usr/bin/rustc` is still the old version. So now we try to make `RUSTC_INSTALL_BINDIR` relative to the sysroot prefix in the first place. r? @Mark-Simulacrum
…, r=varkor Improve non-exhaustiveness handling in usefulness checking The comments around code paths for the `non_exhaustive` feature mention stuff like "we act as if the type had an extra unmatcheable constructor". So I thought I'd make this explicit by defining a special constructor that does exactly this. This makes those code paths a bit more legible and less prone to error.

…ochenkov Move Session fields to CrateStore `allocator_kind` and `injected_panic_runtime` are both query-like, this moves them out of Session and into CrateStore, avoiding the `Once` they previously had by clearing separating initialization and de-initialization.
…a, r=michaelwoerister Move self-profile infrastructure to data structures The single dependency on queries (QueryName) can be fairly easily abstracted via a trait and this further decouples Session from librustc (the primary goal). This is intended as a precursor to moving Session out of librustc, but since that involves lots of smaller steps that move around code I'm splitting it up into separate PRs.
