These features were recently added to std_detect. Features not supported by LLVM 9, the current minimum version for Rust, are commented.
In https://reviews.llvm.org/D102093 lots of things stopped taking the DebugLogging boolean parameter. Mercifully we appear to always set DebugPassManager to false, so I don't think we're losing anything by not passing this parameter.
The makes the code for handling "auto-hide" settings more consistent.
…forms can specialize it
…nieu Update list of allowed aarch64 features I recently added these features to std_detect for aarch64 linux, pending [review](rust-lang/stdarch#1146). I have commented any features not supported by LLVM 9, the current minimum version for Rust. Some (PAuth at least) were renamed between 9 & 12 and I've left them disabled. TME, however, is not in LLVM 9 but I've left it enabled. See rust-lang/stdarch#993
Introduce `sys_common::rt::rtprintpanic!` to replace `sys_common::util` functionality This PR introduces a new macro `rtprintpanic!`, similar to `sys_common::util::dumb_print` and uses that macro to replace all `sys_common::util` functionality.
impl FromStr for proc_macro::Literal
Note that unlike `impl FromStr for proc_macro::TokenStream`, this impl does not permit whitespace or comments. The input string must consist of nothing but your literal.
- `"1".parse::<Literal>()` ⟶ ok
- `"1.0".parse::<Literal>()` ⟶ ok
- `"'a'".parse::<Literal>()` ⟶ ok
- `"\"\n\"".parse::<Literal>()` ⟶ ok
- `"0 1".parse::<Literal>()` ⟶ LexError
- `" 0".parse::<Literal>()` ⟶ LexError
- `"0 ".parse::<Literal>()` ⟶ LexError
- `"/* comment */0".parse::<Literal>()` ⟶ LexError
- `"0/* comment */".parse::<Literal>()` ⟶ LexError
- `"0// comment".parse::<Literal>()` ⟶ LexError

## Use case
```rust
let hex_int: Literal = format!("0x{:x}", int).parse().unwrap();
```
The only way this is expressible in the current API is significantly worse.
```rust
let hex_int = match format!("0x{:x}", int)
.parse::<TokenStream>()
.unwrap()
.into_iter()
.next()
.unwrap()
{
TokenTree::Literal(literal) => literal,
_ => unreachable!(),
};
```
Windows implementation of feature `path_try_exists` Draft of a Windows implementation of `try_exists` (rust-lang#83186). The first commit reorganizes the code so I would be interested to get some feedback on if this is a good idea or not. It moves the `Path::try_exists` function to `fs::exists`. leaving the former as a wrapper for the latter. This makes it easier to provide platform specific implementations and matches the `fs::metadata` function. The other commit implements a Windows specific variant of `exists`. I'm still figuring out my approach so this is very much a first draft. Eventually this will need some more eyes from knowledgable Windows people.

Move `std::memchr` to `sys_common` `std::memchr` is a thin abstraction over the different `memchr` implementations in `sys`, along with documentation and tests. The module is only used internally by `std`, nothing is exported externally. Code like this is exactly what the `sys_common` module is for, so this PR moves it there.
…ou-se Expose `Concurrent` (private type in public i'face) rust-lang#53410 introduced experimental support for custom test frameworks. Such frameworks may wish to build upon `library/test` by calling into its publicly exposed API (which I entirely understand is wholly unstable). However, any that wish to call `test::run_test` cannot currently do so because `test::options::Concurrent` (the type of its `concurrent` parameter) is not publicly exposed.
