Querify local `plugin_registrar_fn` and `proc_macro_decls_static`
Instead of calculating them as part of the `Session`, we do that in the query system.
It's also nice that these queries are already defined for external crates - here, we provide the queries for the local crate.
r? @nikomatsakis
Modify some parser diagnostics to continue evaluating beyond the parser
Continue evaluating further errors after parser errors on:
- trailing type argument attribute
- lifetime in incorrect location
- incorrect binary literal
- missing `for` in `impl Trait for Foo`
- type argument in `where` clause
- incorrect float literal
- incorrect `..` in pattern
- associated types
- incorrect discriminator value variant error
and others. All of these were found by making `continue-parse-after-error` `true` by default to identify errors that would need few changes. There are now only a handful of errors that have any change with `continue-parse-after-error` enabled.
These changes make it so `rust` _won't_ stop evaluation after finishing parsing, enabling type checking errors to be displayed on the existing code without having to fix the parse errors.
Each commit has an individual diagnostic change with their corresponding tests.
CC #48724.
Fix poor worst case performance of set intersection
Specifically, intersection of asymmetrically sized sets when the large set is on the left. See also the [latest answer on stackoverflow](https://stackoverflow.com/questions/35439376/python-set-intersection-is-faster-then-rust-hashset-intersection).
Also applied to the union member, where the effect is much less but still measurable.
Formatted the changed code only, does not increase the error count reported by tidy check, and tried to adhere to the spirit of the unit tests.

r? @alexcrichton
This was originally attempted in #57048 but it was realized that we
could fully remove the crate via the `"unadjusted"` ABI on intrinsics.
This means that all intrinsics in stdsimd are implemented directly
against LLVM rather than using the abstraction layer provided here. That
ends up meaning that this crate is no longer used at all.
This crate developed long ago to implement the SIMD intrinsics, but we
didn't end up using it in the long run. In that case let's remove it!
Remove the `connect_timeout_unroutable` test.
It requires an unreachable IP address, but there is no such thing, and
this has caused it to fail for multiple people.
Fixes#44698, fixes#50065.

Stabilize cfg_target_vendor
This stabilizes the use of `cfg(target_vendor = "...")` and removes the corresponding `cfg_target_vendor` feature. Other unstable cfgs remain behind their existing feature gates.
This functionality was added back in 2015 in #28612 to complete the coverage of target tuples (`<arch><sub>-<vendor>-<os>-<env>`). [RFC 131](https://github.com/rust-lang/rfcs/blob/master/text/0131-target-specification.md) governs the target specification, not including `target_vendor` seems to have just been an oversight. `target_os`, `target_family`, and `target_arch` are stable as of 1.0.0. `target_env` was also not mentioned in RFC 131, was added in #24777, never behind a feature_gate, and insta-stable at 1.1.0.
The functionality is tested in [test/run-pass/cfg/cfg-target-vendor.rs](https://github.com/rust-lang/rust/blob/master/src/test/run-pass/cfg/cfg-target-vendor.rs).
Closes#29718
MetadataOnlyCodegenBackend: run the collector only once
Use the `collect_and_partition_mono_items` query to avoid calling the collector directly twice.
Fixes#57406.
Stabilize core::convert::identity
r? @SimonSapin
fixes https://github.com/rust-lang/rust/issues/53500
This is waiting for FCP to complete but in the interim it would be good to review.
Use structured suggestions for nonstandard style lints
This PR modifies the lints in the nonstandard_style group to use structured suggestions. Note that there's a bit of tricky span calculation going on for the `crate_name` attribute. It also simplifies the code a bit: I don't think the "fallback" suggestions for these lints can actually be triggered.
Fixes#48103.
Fixes#52414.

Fix#57348.
Add dist builder for Armv8-M Mainline
This commit adds the Armv8-M Mainline target in the list of targets that
get their dist components built. It also update the build-manifest so
that this target gets also its dist components uploaded.
I took example on other pull requests doing the same thing for another target to make the changes. Please feel free to comment if things needs to be added or removed.
Doing `./x.py dist --target thumbv8m.main-none-eabi` worked locally so I assume that this will also work on the CI.
It will (I think) however need a new release of alexcrichton/cc-rs to include the pull request alexcrichton/cc-rs#363 @alexcrichton
I hope to do the HardFloat version (`thumbv8m.main-none-eabihf`) and Baseline (`thumbv8m.base-none-eabi`) later, as fixes need to be done on compiler-builtins first to support those.
