make MIR graphviz generation use gsgdt
gsgdt [https://crates.io/crates/gsgdt] is a crate which provides an
interface for stringly typed graphs. It also provides generation of
graphviz dot format from said graph.
This is the first in a series of PRs on moving graphviz code out of rustc into normal crates and then implementating graph diffing on top of these crates.

Create `rustc_type_ir`
Decided to start small 😄
This PR creates a `rustc_type_ir` crate as part of the WG-Traits plan to create a shared type library.
~~There already exists a `rustc_ty` crate, so I named the new crate `rustc_ty_library`. However I think it would make sense to rename the current `rustc_ty` to something else (e.g. `rustc_ty_passes`) to free the name for this new crate.~~

This commit updates the `library/backtrace` submodule which primarily
pulls in support for split-debuginfo on macOS, avoiding the need for
`dsymutil` to get run to get line numbers and filenames in backtraces.
Add lint for panic!("{}")
This adds a lint that warns about `panic!("{}")`.
`panic!(msg)` invocations with a single argument use their argument as panic payload literally, without using it as a format string. The same holds for `assert!(expr, msg)`.
This lints checks if `msg` is a string literal (after expansion), and warns in case it contained braces. It suggests to insert `"{}", ` to use the message literally, or to add arguments to use it as a format string.
This lint is also a good starting point for adding warnings about `panic!(not_a_string)` later, once [`panic_any()`](https://github.com/rust-lang/rust/pull/74622) becomes a stable alternative.
Upgrade dlmalloc to version 0.2
In preparation of adding dynamic memory management support for SGXv2-enabled platforms, the dlmalloc crate has been refactored. More specifically, support has been added to implement platform specification outside of the dlmalloc crate. (see https://github.com/alexcrichton/dlmalloc-rs/pull/15)
This PR upgrades dlmalloc to version 0.2 for the `wasm` and `sgx` targets.
As the dlmalloc changes have received a positive review, but have not been merged yet, this PR contains a commit to prevent tidy from aborting CI prematurely.

Fix displaying errors when rustbook tests fail.
This ensures that output from mdbook is displayed when running the rustbook wrapper. I believe this was a regression as a result of #69115 where it was changed from running `rustdoc` directly to using rustbook.

Add support for SHA256 source file hashing
Adds support for `-Z src-hash-algorithm sha256`, which became available in LLVM 11.
Using an older version of LLVM will cause an error `invalid checksum kind` if the hash algorithm is set to sha256.

Initialize tracing subscriber in compiletest tool
The logging in compiletest was migrated from log crate to a tracing, but
the initialization code was never changed, so logging is non-functional.
Initialize tracing subscriber using default settings.
Update `compiler_builtins` to 0.1.36
So, the libc build with cargo's `build-std` feature emits a lot of warnings like:
```
warning: a method with this name may be added to the standard library in the future
--> /home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/compiler_builtins-0.1.35/src/int/udiv.rs:98:23

98 | q = n << (<$ty>::BITS - sr);
| ^^^^^^^^^^^
...
268 | udivmod_inner!(n, d, rem, u128)
| ------------------------------- in this macro invocation
|
= warning: once this method is added to the standard library, the ambiguity may cause an error or change in behavior!
= note: for more information, see issue #48919 <rust-lang/rust/issues/48919>
= help: call with fully qualified syntax `Int::BITS(...)` to keep using the current method
= help: add `#![feature(int_bits_const)]` to the crate attributes to enable `num::<impl u128>::BITS`
= note: this warning originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)
```
(You can find the full log in https://github.com/rust-lang/libc/runs/1283695796?check_suite_focus=true for example.)
0.1.36 contains https://github.com/rust-lang/compiler-builtins/pull/332 so this version should remove this warning.

Upgrade to measureme 9.0.0
I believe I did this correctly but there's still a reference to `measureme@0.7.1` coming from `rustc-ap-rustc_data_structures` and I'm not sure how to resolve that.

We'll also need to deploy the new version of the tools on perf.rlo.
revise Hermit's mutex interface to support the behaviour of StaticMutex
rust-lang/rust#77147 simplifies things by splitting this Mutex type into two types matching the two use cases: StaticMutex and MovableMutex. To support the new behavior of StaticMutex, we move part of the mutex implementation into libstd.
The interface to the OS changed. Consequently, I removed a few functions, which aren't longer needed.
