Compile address sanitizer test with debuginfo
This makes error-pattern to match regardless of current
configuration of `rust.debuginfo-level-tests` in `config.toml`.
Change DIBuilderCreateEnumerator signature to match LLVM 9
* Change DIBuilderCreateEnumerator signature to match LLVM 9 C API.
* Use provided is unsigned flag when emitting enumerators.
mir-interpret: add method to read wide strings from Memory
Implemented *step2* from [instructions](https://github.com/rust-lang/miri/issues/707#issuecomment-561564057) laid out in rust-lang/miri#707.
Added 2 new methods to struct `rustc_mir::interpret::InterpCx`.
* `read_os_str_from_wide_str` (src/librustc_mir/interpret/operand.rs)
* `write_os_str_to_wide_str` (src/librustc_mir/interpret/place.rs)
- used existing logic implemented in [MIRI/src/eval.rs](94732aaf7b/src/eval.rs (L132-L141))
These methods are intended to be used for environment variable emulation in Windows.

More documentation and simplification of BTreeMap's internals
Salvage the documentation and simplification from #67980, without changing the type locked down by debuginfo.

Miri visitor: detect primitive types based on type, not layout (also, more tests)
I also converted the union-based transmutes to use `mem::transmute` for increased readability.

check_binding_alt_eq_ty: improve precision wrt. `if let`
Follow up to https://github.com/rust-lang/rust/pull/69452 -- this tweaks the `check_binding_alt_eq_ty` logic wrt. wording so that `if let` doesn't include "in this arm" (because there can only ever be one arm).

Clean up unstable book
- #58402's feature was renamed to `tidy_test_never_used_anywhere_else` and it is now used for tidy only
- `read_initializer` link is wrong and the doc should be auto-generated so removed
- Add dummy doc for `link_cfg`
- Stop generating `compiler_builtins_lib` doc in favor of b8ccc0f8a6
- Make `rustc_attrs` tracking issue "None"
Turn trailing tokens in `assert!()` into hard errors
I didn't have time to build the compiler and thus edited the tests manually, I hope it will still pass.
Closes#69531

Add `Layout::dangling()` to return a well-aligned `NonNull<u8>`
Adds a convenient function to `Layout` to create a `NonNull<u8>` out of a layout to be returned on ZST allocations.
This is the first item on the roadmap to support ZSTs in `AllocRef`: https://github.com/rust-lang/wg-allocators/issues/38#issuecomment-595861542

On mismatched delimiters, only point at empty blocks that are in the same line
We point at empty blocks when we have mismatched braces to detect cases where editors auto insert `}` after writing `{`. Gate this to only the case where the entire span is in the same line so we never point at explicitly empty blocks.
resolve, inconsistent binding mode: tweak wording
Now that we can have e.g. `let Ok(x) | Err(x) = res;`, it's no longer appropriate to refer to "the same *match arm*", so let's tweak the wording.
r? @estebank
Pass correct place to `discriminant_switch_effect`
PR #69562, which fixed a bug that was causing clippy to ICE, mistakenly passed the place holding the *result* of `Rvalue::Discriminant` instead of the place holding its *operand* to `apply_discriminant_switch_effect` as the enum place. As a result, no effect was applied at all, and we lost the perf benefits from marking inactive enum variants as uninitialized.
**edit:** The regression test has been split into #69744.
