Stabilize `unrestricted_attribute_tokens`
In accordance with a plan described in https://internals.rust-lang.org/t/unrestricted-attribute-tokens-feature-status/8561/3.
Delimited non-macro non-builtin attributes now support the same syntax as macro attributes:
```
PATH
PATH `(` TOKEN_STREAM `)`
PATH `[` TOKEN_STREAM `]`
PATH `{` TOKEN_STREAM `}`
```
Such attributes mostly serve as inert proc macro helpers or tool attributes.
To some extent these attributes are de-facto stable due to a hole in feature gate checking (feature gating is done too late - after macro expansion.)
So if macro *removes* such helper attributes during expansion (and it must remove them, unless it's a derive macro), then the code will work on stable.
Key-value non-macro non-builtin attributes are now restricted to bare minimum required to support what we support on stable - unsuffixed literals (https://github.com/rust-lang/rust/issues/34981).
```
PATH `=` LITERAL
```
(Key-value macro attributes are not supported at all right now.)
Crater run in https://github.com/rust-lang/rust/pull/57321 found no regressions for this change.
There are multiple possible ways to extend key-value attributes (https://github.com/rust-lang/rust/pull/57321#issuecomment-451574065), but I'd expect an RFC for that and it's not a pressing enough issue to block stabilization of delimited attributes.
Built-in attributes are still restricted to the "classic" meta-item syntax, nothing changes here.
https://github.com/rust-lang/rust/pull/57321 goes further and adds some additional restrictions (more consistent input checking) to built-in attributes.
Closes https://github.com/rust-lang/rust/issues/55208

deprecate before_exec in favor of unsafe pre_exec
Fixes https://github.com/rust-lang/rust/issues/39575
As per the [lang team decision](https://github.com/rust-lang/rust/issues/39575#issuecomment-442993358):
> The language team agreed that before_exec should be unsafe, and leaves the details of a transition plan to the libs team.
Cc @alexcrichton @rust-lang/libs how would you like to proceed?

Make overflowing and wrapping negation const
Remember that the signed and unsigned versions are slightly different here, so there's four functions made const instead of just two.

Stabilize str::escape_* methods with new return types…
… that implement `Display` and `Iterator<Item=char>`, as proposed in FCP: https://github.com/rust-lang/rust/issues/27791#issuecomment-376864727

Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).
r? @steveklabnik
Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

Avoid committing to autoderef in object method probing
This fixes the "leak" introduced in #57835 (see test for details, also apparently #54252 had no tests for the "leaks" that were fixed in it, so go ahead and add one).
Maybe beta-nominating because regression, but I'm against landing things on beta we don't have to.

Add intrinsic to create an integer bitmask from a vector mask
This PR adds a new simd intrinsic: `simd_bitmask(vector) -> unsigned integer` that creates an integer bitmask from a vector mask by extracting one bit of each vector lane.
This is required to implement: https://github.com/rust-lang-nursery/packed_simd/issues/166 .
EDIT: the reason we need an intrinsics for this is that we have to truncate the vector lanes to an `<i1 x N>` vector, and then bitcast that to an `iN` integer (while making sure that we only materialize `i8`, ... , `i64` - that is, no `i1`, `i2`, `i4`, types), and we can't do any of that in a Rust library.

Change bounds on `TryFrom` blanket impl to use `Into` instead of `From`
This is from this [comment](https://github.com/rust-lang/rust/issues/33417#issuecomment-447111156) I made.
This will expand the impls available for `TryFrom` and `TryInto`, without losing anything in the process.
