rustdoc: Add option to persist doc test executables
Fixes #37048.
This is the initial version of the code so the doctest executables can be used for stuff like code coverage (specifically https://github.com/xd009642/tarpaulin/issues/13) the folders it goes into were just a first idea, so any better ones are welcome.
Right now it creates a directory structure like:
```
given_path/
|_____ <filename>_rs_<linenum>/
|_____ ...
|_____ <filename>_rs_<linenum>/
|_____ rust_out
```
I couldn't figure out where it actually outputs the file w/ the name, I suspect its somewhere deeper in the compiler.
It also adds the unstable `--persist-doctests` flag to `rustdoc` that enables this behavior.

Always calculate glob map but only for glob uses
Previously calculating glob map was *opt-in*, however it did record node id -> ident use for every use directive. This aims to see if we can unconditionally calculate the glob map and not regress performance.
Main motivation is to get rid of some of the moving pieces and simplify the compilation interface - this would allow us to entirely remove `CrateAnalysis`. Later, we could easily expose a relevant query, similar to the likes of `maybe_unused_trait_import` (so using precomputed data from the resolver, but which could be rewritten to be on-demand).

Local perf run showed mostly noise (except `ctfe-stress-*`) but I'd appreciate if we could do a perf run run here and double-check that this won't regress performance.

rustc: Remove platform intrinsics crate
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!

Another way to think of `iter::once_with()` is that it's a function that converts `FnOnce() -> T` into `Iterator<Item = T>`.
If this seems like a reasonable addition, I'll open a tracking issue and update the `#[feature(...)]` attributes.

forbid manually impl'ing one of an object type's marker traits
This shouldn't break compatibility for crates that do not use
`feature(optin_builtin_traits)`, because as the test shows, it is
only possible to impl a marker trait for a trait object in the crate the
marker trait is defined in, which must define
`feature(optin_builtin_traits)`.
Prior to 1.12.0 we dropped both `_x` and `_y` before the rest of their
respective parameters, since then we dropped `_x` and `_y` after. The
original order appears to be the correct order, as the value created
later is dropped first, so we revert to that order and add a test for
it.
While this is technically a breaking change, I can't work out how
anyone could be relying on this without making their code very
brittle. If this is considered to be too likely to break real world code
then I can revert the change and change the test to check for the
current order.

Upgrade x86_64-fortanix-unknown-sgx platform support to tier 2
## Overview
1. This PR upgrades x86_64-fortanix-unknown-sgx platform support to tier 2 (std only) by setting up build automation for this target.
1. For supporting unwinding, this target needs to link to a port of LLVM's libunwind (more details could be found in #56979), which will be distributed along with the Rust binaries (similar to the extra musl objects)
### Building and copying libunwind:
We have added a new build script (`build-x86_64-fortanix-unknown-sgx-toolchain.sh`) that will run while the container is built. This will build `libunwind.a` from git source.
While the container is built, the persistent volumes where obj/ gets created aren't yet mapped. As a workaround, we copy the built `libunwind.a` to `obj/build/x86_64-unknown-linux-gnu/stage2/lib/rustlib/x86_64-fortanix-unknown-sgx/lib/` after x.py runs.
If any reviewer knows of a better solution, please do tell.

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.

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).

Simplify foreign type rendering.
Simplified foreign type rendering by switching from tables to flexbox. Also, removed some seemingly extraneous elements like “ghost” spans.
Reduces element count on the `std::iter::Iterator` page by 30%. On my laptop it drops Iterator page load time from ~15s to ~10s. Frame times during scrolling are a hair lower too.
Known visual changes (happy to tweak based on feedback):
* The main `impl ...` headers are now getting the default, larger, h3 font size. This was an accident, but I liked how it turned out so I didn't fix it.
* There's a hair less vertical spacing between the end of a where block and the start of the next fn. Now, all spacing is consistent. I think this looks a bit worse. I may tweak vertical spacing more here or in a follow-up that cleans up vertical spacing more broadly.
* "[src]" links are all sized at 17px. A few were 19px in the original.
I haven't yet done heavy cross-browser or cross-crate testing. I was hoping to get a quick thumbs up or thumbs down here at this first draft, then if this is on the right track I'll spend some time on that testing.
