Add PartialEq impls for Vec <-> slice
This is a follow-up to #71660 and rust-lang/rfcs#2917 to add two more missing vec/slice PartialEq impls:
```
impl<A, B> PartialEq<[B]> for Vec<A> where A: PartialEq<B> { .. }
impl<A, B> PartialEq<Vec<B>> for [A] where A: PartialEq<B> { .. }
```
Since this is insta-stable, it should go through the `@rust-lang/libs` FCP process. Note that I used version 1.47.0 for the `stable` attribute because I assume this will not merge before the 1.46.0 branch is cut next week.

Add c as a shorthand check alternative for new options #77603
There is a missing "c" that is a shorthand for "check" in newly added match arm for handling check-specific options.
Let backends access span information
Sometimes, a backend may need to emit warnings, errors, or otherwise need to know the span of the current item in a basic block. So, add a `set_span` method to give the backend that information.
The `set_source_location` method already partially does this, however, it's disabled when debug info is disabled. There needs to be a way to unconditionally provide the span.
inliner: use caller param_env
We used the callee param env instead of the caller param env by accident in #77430, this PR fixes that and caches it in the `Inliner` struct.

Update to chalk 0.31
Gonna assign @nikomatsakis to the review here, but since he is pretty busy recently, if anyone else wants to review this, that would be much appreciated.

Fix suggestions for x.py setup
#76631 introduced a new `setup` command to x.py
By default the command prompts for a profile to use:
```
Welcome to the Rust project! What do you want to do with x.py?
a) Contribute to the standard library
b) Contribute to the compiler
c) Contribute to the compiler, and also modify LLVM or codegen
d) Install Rust from source
```
and then displays command suggestions, depending on which profile was chosen. However [the mapping between chosen profile](9cba260df0/src/bootstrap/setup.rs (L75-L85)) and [suggestion](9cba260df0/src/bootstrap/setup.rs (L42-L47)) isn't exact, leading to suggestions not being shown if the user presses `c` or `d`. (because "c" is translated to "llvm" and "d" to "maintainer", but suggestions trigger for "codegen" and "user" respectively)
A more thorough refactor would stop using "strings-as-type" to make sure this kind of error doesn't happen, but it may be overkill for that kind of "script" program?

Support static linking with glibc and target-feature=+crt-static
With this change, it's possible to build on a linux-gnu target and pass
RUSTFLAGS='-C target-feature=+crt-static' or the equivalent via a
`.cargo/config.toml` file, and get a statically linked executable.
Update to libc 0.2.78, which adds support for static linking with glibc.
Add `crt_static_respected` to the `linux_base` target spec.
Update `android_base` and `linux_musl_base` accordingly. Avoid enabling
crt_static_respected on Android platforms, since that hasn't been
tested.
Closes https://github.com/rust-lang/rust/issues/65447.
Add a command to install a git hook to automatically run `x.py test tidy --bless`
Some folks (such as myself) would probably find a lot of convenience in a pre-commit hook that automatically runs tidy before committing, to avoid burning CI time learning that your commit wasn't tidy.
I'm absolutely positive I have missed some stuff. I basically just got this to where you can run `./x.py run install-git-hook` and then clicked the commit button. Please let me know what else you'd like me to add before this can be merged!
[rustc-dev-guide companion PR](https://github.com/rust-lang/rustc-dev-guide/pull/848)
Sometimes, a backend may need to emit warnings, errors, or otherwise
need to know the span of the current item in a basic block. So, add a
set_span method to give the backend that information.
Separate projection bounds and predicates
Follow up to #72788.
- Rename `projection_predicates` to `item_bounds`
- Separate bounds on associated types (the things after the `:` in `type X: ...`) and opaque types (the things after `impl`) from predicates.
- Projection candidates now have the correct nested obligations
- Trait object candidates now check that the associated types on the trait object satisfy their bounds as nested obligations
- Type alias impl trait types are now checked (#73035)
- `feature(generic_associated_types)` no longer changes how we handle bounds (#73816)
Opening for a perf and crater runs.
r? `@nikomatsakis`
Only check the own predicates of associated types when confirming
projection candidates.
Also consider implied bounds when comparing trait and impl methods.
Normalizing `<dyn Iterator<Item = ()> as Iterator>::Item` no longer
requires selecting `dyn Iterator<Item = ()>: Iterator`. This was
previously worked around by using a special type-folder to normalize
things.
Bounds of the form `type Future: Future<Result=Self::Result>` exist in
some ecosystem crates. To validate these bounds for trait objects we
need to normalize `Self::Result` in a way that doesn't cause a cycle.
