Although `stack_overflow::init` runs very early in the process, even
before `main`, there may already be signal handlers installed for things
like the address sanitizer. In that case, just leave it alone, and don't
bother trying to allocate our own signal stacks either.
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

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
r? @Centril do you want to queue the Crater experiment?
