Rollup merge of #60045 - estebank:suggest-std, r=petrochenkov
Suggest appropriate path when calling associated item on bare types
When looking at the documentation for `std::f32` or `std::str`, for
example, it is easy to get confused and assume `std::f32` and `f32`
are the same thing. Because of this, it is not uncommon to attempt
writing `f32::consts::PI` instead of the correct
`std::f32::consts::PI`. When encountering the former, which results
in an access error due to it being an inexistent path, try to access
the same path under `std`. If this succeeds, this information is
stored for later tweaking of the final E0599 to provide an
appropriate suggestion.

Implement event filtering for self-profiler.
This is a first sketch for event filtering in the self-profiler, something that we'll want in order to keep profiling overhead low in the common case. The PR contains the commits from https://github.com/rust-lang/rust/pull/59515 and, for the moment, is meant for performance testing.

This suggestion applies to both E0233 and E0599 and is only checked
when the first ident of a path corresponds to a primitive type.
Rollup merge of #60037 - eddyb:actually-its-param, r=estebank
Resolve inconsistency in error messages between "parameter" and "variable".
The inconsistency was introduced in 104fe1c4db24f860b890dfd25577f23ee111279a (#33619), when a label saying `type variable` was added to an error with a message talking about `type parameters`.
Given that `parameter` is far more prevalent when referring to generics in the context of Rust, IMO it should be that in both the message and the label.
Rollup merge of #59984 - gluyas:collections-with_capacity-doc-fix, r=rkruppe
Remove collection-specific `with_capacity` documentation from `std::collections`
Fixes #59931
The style of `std::collections` module doc is very much a beginner friendly guide, and documenting niche, collection-specific behaviour feels out of place, if not brittle.
The note about `VecDeque` is outdated (see issue), and while `Vec` probably won't change its guarantees any time soon, the users who are interested in its allocation properties will find that in its own documentation.
Auto merge of #59527 - matklad:sized-index, r=Centril
Add test checking that Index<T: ?Sized> works
I've noticed that we have an `Idx: ?Sized` bound on the **index** in the `Index`, which seems strange given that we accept index by value. My guess is that it was meant to be removed in https://github.com/rust-lang/rust/pull/23601, but was overlooked.
If I remove this bound, `./x.py src/libstd/ src/libcore/` passes, which means at least that this is not covered by test.
I think there's three things we can do here:
* run crater with the bound removed to check if there are any regressions, and merge this, to be consistent with other operator traits
* run crater, get regressions, write a test for this with a note that "hey, we tried to fix it, its unfixable"
* decide, in the light of by-value DSTs, that this is a feature rather than a bug, and add a test

EDIT: the forth alternative is that there exist a genuine reason why this is the case, but I failed to see it :D

Miri: refactor new allocation tagging
Tagging and initializing `AllocExtra` now go hand-in-hand so one cannot forget to do one when doing the other. In particular, `memory.allocate` is now much easier to use correctly (because it will already return a tagged pointer).
Auto merge of #60027 - jethrogb:jb/sgx-reentry-abort, r=cramertj
SGX target: change re-entry abort logic
Even though re-entry after exit is generally not acceptable, there is a race condition where the enclave thinks it's exited but userspace doesn't know that yet. An entry during that time will currently result in an enclave panic (see https://github.com/rust-lang/rust/pull/59997#issuecomment-483846291, https://github.com/rust-lang/rust/pull/60003#issuecomment-483888170). Instead of panicking, just do a regular exit on re-entry.
Auto merge of #59879 - ebarnard:patch-1, r=alexcrichton
Add a comment explaining why SecRandomCopyBytes is not used on MacOS
SecRandomCopyBytes is [available since MacOS 10.7](https://developer.apple.com/documentation/security/1399291-secrandomcopybytes?language=objc) which is the minimum supported version and which was suggested in https://github.com/rust-lang/rust/pull/58901#issuecomment-470188115 is the earliest version currently in use.
This matches the behaviour of other platforms which have a random number generator syscall available.
Auto merge of #59769 - RalfJung:compiletest-normalization, r=alexcrichton
compiletest normalization: preserve non-JSON lines such as ICEs
Currently, every non-JSON line from stderr gets normalized away when compiletest normalizes the output. In particular, ICEs get normalized to the empty output. That does not seem desirable, so this changes normalization to preserve non-JSON lines instead.
Also see https://github.com/laumann/compiletest-rs/issues/169: because of that bug, Miri currently *looks* green in the toolstate, but some tests ICE. That same bug is likely no longer present in latest compiletest because the error code gets checked separately, but it still seems like a good idea to also make sure that ICEs are considered stderr output:
This change found an accidental user-visible `error!` in CTFE validation (fixed), and a non-deterministic panic when there are two `main` symbols (not fixed, no idea where this comes from). Both got missed before because non-JSON output got ignored.

rustdoc: use --static-root-path for settings.js
At the time i was writing https://github.com/rust-lang/docs.rs/pull/332, i noticed that the `settings.js` file that was being loaded was not being loaded from the `--static-root-path`. This PR fixes that so that users on docs.rs can effectively cache this file.

Auto merge of #59926 - pietroalbini:android-sdk-manager, r=alexcrichton
ci: use a custom android sdk manager with pinning and mirroring
Google's own sdkmanager has two issues that make it unsuitable for us:
* Mirroring has to be done manually, which is annoying because we need to figure out on our own all the URLs to copy (I couldn't find any documentation when building this PR, had to use mitmproxy).
* There is no support for pinning, which means an update on Google's side can break our CI, as it happened multiple times.
This PR replaces all our usage of sdkmanager with a custom Python script which mimics its behavior, but with the two issues fixes.
sdkmanager's logic for installing packages is thankfully very simple: the package name (like `system-images;android-18;default;armeabi-v7a`) is the directory where the package should live (with `;` replaced with `/`), so to install a package we only need to extract its contents in the right directory.
