Revert "correct subtle bug in the type variable code"

This reverts commit ccd92c2a4e.

This commit is the source of a major perf regression, and was not
intended to be included in #47861. At some point I must have
accidentally re-added the commit.

Fixes #48660.

Replace Rc with Lrc for shared data

This replaces `Rc`s reachable from `TyCtxt` with `Lrc`. This has no effect unless `cfg(parallel_queries)` is set. It also contains a fix for the `Decodable` impl for `Arc`.

c72537f204 std: Add arch and simd modules
This commit imports the `stdsimd` crate into the standard library,
creating an `arch` and `simd` module inside of both libcore and libstd.
Both of these modules are **unstable** and will continue to be so until
RFC 2335 is stabilized.

As a brief recap, the modules are organized as so:

* `arch` contains all current architectures with intrinsics, for example
  `std::arch::x86`, `std::arch::x86_64`, `std::arch::arm`, etc. These
  modules contain all of the intrinsics defined for the platform, like
  `_mm_set1_epi8`.
* In the standard library, the `arch` module also exports a
  `is_target_feature_detected` macro which performs runtime detection to
  determine whether a target feature is available at runtime.
* The `simd` module contains experimental versions of strongly-typed
  lane-aware SIMD primitives, to be fully fleshed out in a future RFC.

The main purpose of this commit is to start pulling in all these
intrinsics and such into the standard library on nightly and allow
testing and such. This'll help allow users to easily kick the tires and
see if intrinsics work as well as allow us to test out all the
infrastructure for moving the intrinsics into the standard library.

2269ff521f Remove print_what_bootstrap_means
It was an existing solution to tell the user why a --help command
takes a long time to process. However, it would only print if the
stage0 rust compiler needed to be downloaded, it came after
update_submodules (which took a long time), and it was immediately
followed by download messages and loading bars, meaning users could
easily gloss over the message.

This commit also moves the help message out of main(), and instead
puts it at the top of bootstrap(). main() is intended to be minimal,
only handling error messages.

2e9d9d48d5 rustc: More stable hashes of command line arguments
Currently rustc isn't always the best at producing deterministic builds of a
crate when the source directory of a crate is changed. This is happening due to
what appears two different sources:

* First the `-L` paths passed to rustc are hashed into the crate hash. These
  paths through Cargo are typically absolute paths that can vary if the build
  directory changes.

* Next the paths passed to `--extern` are also hashed which like `-L` can change
  if the build directory changes.

This commit fixes these two sources of nondeterminism by ensuring that avoiding
tracking the hashes of these arguments on the command line. For `-L` paths
they're either related to loading crates (whose hashes are tracked elsewhere) or
native librarise used in the linking phase (which isn't incremental). The
`--extern` paths are similar in that they're related to crate resolution which
is already tracked independently of the command line arguments.

Closes #48019

rustc: Tweak funclet cleanups of ffi functions

This commit is targeted at addressing #48251 by specifically fixing a case where
a longjmp over Rust frames on MSVC runs cleanups, accidentally running the
"abort the program" cleanup as well. Added in #46833 `extern` ABI functions in
Rust will abort the process if Rust panics, and currently this is modeled as a
normal cleanup like all other destructors.

Unfortunately it turns out that `longjmp` on MSVC is implemented with SEH, the
same mechanism used to implement panics in Rust. This means that `longjmp` over
Rust frames will run Rust cleanups (even though we don't necessarily want it
to). Notably this means that if you `longjmp` over a Rust stack frame then that
probably means you'll abort the program because one of the cleanups will abort
the process.

After some discussion on IRC it turns out that `longjmp` doesn't run cleanups
for *caught* exceptions, it only runs cleanups for cleanup pads. Using this
information this commit tweaks the codegen for an `extern` function to
a catch-all clause for exceptions instead of a cleanup block. This catch-all is
equivalent to the C++ code:

    try {
        foo();
    } catch (...) {
        bar();
    }

and in fact our codegen here is designed to match exactly what clang emits for
that C++ code!

With this tweak a longjmp over Rust code will no longer abort the process. A
longjmp will continue to "accidentally" run Rust cleanups (destructors) on MSVC.
Other non-MSVC platforms will not rust destructors with a longjmp, so we'll
probably still recommend "don't have destructors on the stack", but in any case
this is a more surgical fix than #48567 and should help us stick to standard
personality functions a bit longer.

75b8c10391 Rollup merge of #48522 - etaoins:fix-find-width-of-character-at-span-bounds-check, r=estebank
Fix find_width_of_character_at_span bounds check

Commit 0bd96671f0 added bounds checking of our current target byte position to prevent infinite loops. Unfortunately it was comparing the file-relative `target` versus the global `file_start_pos` and `file_end_pos`.

The result is failing to detect multibyte characters unless their file-relative offset fit within their global offset. This causes other parts of the compiler to generate spans pointing to the middle of a
multibyte character which will ultimately panic in `bytepos_to_file_charpos`.

Fix by comparing the `target` to the total file size when moving forward and doing checked subtraction when moving backwards. This should preserve the intent of the bounds check while removing the offset confusion.

* Fixed rust-lang-nursery/rust-toolstate#2, a comment will be posted to the PR if the toolstate changed
* Toolstate regression will be rejected at the last week of the 6-week cycle (currently entirely date-based).
* Implemented https://internals.rust-lang.org/t/the-current-submodule-setup-is-not-tenable/6593, moved doc tests of Nomicon, Reference, Rust-by-Example and The Book to the "tools" job and thus allowed to fail like other external tools.
