update test cases for vxWorks
issue-2214.rs: lgamma is lgamma on vxWorks
ignore process-envs.rs and process-remove-from-env.rs as there is no 'env' on vxWorks
Remove derives `Encodable`/`Decodable` and unstabilize attribute `#[bench]`
`Encodable` and `Decodable` were deprecated before 1.0 and emitted an unsuppressable warning all this time.
`#[bench]` is a part of the custom test framework feature and cannot be used meaningfully on stable, only as `cfg(false)`.
Crater results can be found in https://github.com/rust-lang/rust/pull/62507#issuecomment-513850732 and below.
This PR also reroutes the tracking issue for `feature(test)` from #27812 (compiler internals) to #50297 (custom test frameworks).
Closes https://github.com/rust-lang/rust/issues/62048
Some fixes for i686-msvc and Windows have landed on the `backtrace`
crate but hadn't made their way here yet. Let's update that and see if
it passes CI.
rustc: Compile the `fmt_macros` crate as an rlib
I think this was left out by accident from the "convert everything to
rlibs" commit, there's no need for this to be a dylib just as everything
else doesn't need to be a dylib!
`const fn`-ify `std::any::type_name` as laid out in #63084
A test, based on the one I added when I implemented support for the underlying `core::intrinsics::type_name` being allowed in `const fn` contexts, is included.
Turn `INCOMPLETE_FEATURES` into lint
We do this because it is annoying to see the warning when building rustc and because this is better from a "separation of concerns" POV.
The drawback to this change is that this will respect `--cap-lints`.
Also note that this is not a buffered lint so if there are fatal parser errors then the lint will not trigger.

Unsupport the `await!(future)` macro
Unsupport the `await!(future)` "macro" and recognize it in error recovery instead.
The `future.await` syntax has been on nightly since 2019-05-08.
This was 55 days ago which is 1.31 releases ago.
Closes https://github.com/rust-lang/rust/issues/60610.

rustc: Stabilize options for pipelined compilation
This commit stabilizes options in the compiler necessary for Cargo to
enable "pipelined compilation" by default. The concept of pipelined
compilation, how it's implemented, and what it means for rustc are
documented in #60988. This PR is coupled with a PR against Cargo
(rust-lang/cargo#7143) which updates Cargo's support for pipelined
compliation to rustc, and also enables support by default in Cargo.
(note that the Cargo PR cannot land until this one against rustc lands).
The technical changes performed here were to stabilize the functionality
proposed in #60419 and #60987, the underlying pieces to enable pipelined
compilation support in Cargo. The issues have had some discussion during
stabilization, but the newly stabilized surface area here is:
* A new `--json` flag was added to the compiler.
* The `--json` flag can be passed multiple times.
* The value of the `--json` flag is a comma-separated list of
directives.
* The `--json` flag cannot be combined with `--color`
* The `--json` flag must be combined with `--error-format=json`
* The acceptable list of directives to `--json` are:
* `diagnostic-short` - the `rendered` field of diagnostics will have a
"short" rendering matching `--error-format=short`
* `diagnostic-rendered-ansi` - the `rendered` field of diagnostics
will be colorized with ansi color codes embedded in the string field
* `artifacts` - JSON blobs will be emitted for artifacts being emitted
by the compiler
The unstable `-Z emit-artifact-notifications` and `--json-rendered`
flags have also been removed during this commit as well.

Properly check the defining scope of existential types
Fixes#52632
Existential types (soon to be 'impl trait' aliases) can either be
delcared at a top-level crate/module scope, or within another item such
as an fn. Previously, we were handling the second case incorrectly when
recursively searching for defining usages - we would check children of
the item, but not the item itself. This lead to us missing closures
that consituted a defining use of the existential type, as their opaque
type instantiations are stored in the TypeckTables of their parent
function.
This commit ensures that we explicitly visit the defining item itself,
not just its children.
Make generic parameters always use modern hygiene
* E0263 (lifetime parameter declared twice in the same scope) now compares modernized identifiers.
* Const parameters are now resolved with modern hygiene.

This is a modified version of the test I added previously. The difference is this version implements a wrapper around std::any::type_name versus core::intrinsics::type_name, in order to show that it works as desired / intended.
I think this was left out by accident from the "convert everything to
rlibs" commit, there's no need for this to be a dylib just as everything
else doesn't need to be a dylib!
Ignore test cases that are not supported by vxWorks
bypass x86stdcall.rs for vxworks
ignore wait-forked-but-failed-child.rs as there is no command 'ps' on vxWorks
ignore process-sigpipe.rs as there is no 'sh' on vxWorks
ignore core-run-destroy.rs as there is no 'cat' and 'sleep' on vxWorks
cleanup: Remove some language features related to built-in macros
They are now library features.
Cleanup after https://github.com/rust-lang/rust/pull/62086.
The unstable book files are moved because tidy complained.
