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`.

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.

I also converted the union-based transmutes to use `mem::transmute` for increased readability.
