…od calls on raw pointers

Create the rustc_sanitizers crate and move the source code for the CFI
and KCFI sanitizers to it.

Co-authored-by: David Wood <[email protected]>

To separate `ReifyReason::FnPtr` from `ReifyReason::VTable`, we
hyphenated the shims. Hyphens are not actually legal, but underscores
are, so use those instead.

There is already a workaround in `compiletest` to deal with custom
`CARGO_HOME` using `-Zignore-directory-in-diagnostics-source-blocks={}`.
A similar need exists when dependencies come from the local `vendor`
directory, which distro builds often use, so now we ignore that too.

Also, `issue-21763.rs` was normalizing `hashbrown-` paths, presumably
expecting a version suffix, but the vendored path doesn't include the
version. Now that matches `[\\/]hashbrown` instead.

To reduce redundancy, we now internalize the BinOp instead of
duplicating the `ty()` function body.

sanitizers: Create the rustc_sanitizers crate

Create the `rustc_sanitizers` crate and move the source code for the CFI and KCFI sanitizers to it. The tracking issue for reviewing and moving sanitizers into a compiler crate is rust-lang#123619. This is part of our work to organize and stabilize support for the sanitizers. (See our roadmap at https://hackmd.io/`@rcvalle/S1Ou9K6H6.)`

[rustdoc] [GUI tests] Make theme switching closer to reality

Better to actually perform actions user do rather than only testing the change through local storage.

As for `browser-ui-test` update: I updated `puppeteer` version (to `0.19.4`) and fixed a bug when displaying the file if it came from an `include`.

rustdoc: slightly clean up the synthesis of blanket impls

Small follow-up to rust-lang#123340 as promised in rust-lang#123340 (comment). No functional changes whatsoever.

* inline the over-engineered “type namespace” (struct) `BlanketImplFinder` just like I did with `AutoTraitFinder` in rust-lang#123340
* use the new `synthesize_*` terminology over the old nondescript / misleading `get_*` one
* inline a `use super::*;` (not super modular, lead to `clean/mod.rs` (!) accumulating cruft)
* use `tracing` properly
