LLVM 10 includes a009a60 which will
print value numbers for unnamed func args.

Update these tests to be in line with the referenced clang tests.
It isn't clear to me if this is a bug or not, hence the FIXME

Make `PolyTraitRef::self_ty` return `Binder<Ty>`

This came up during review of rust-lang#71618. The current implementation is the same as a call to `skip_binder` but harder to audit. Make it preserve binding levels and add a call to `skip_binder` at all use sites so they can be audited as part of rust-lang#72507.

run-make regression test for issue rust-lang#70924.

Sometime after my PR rust-lang#72767 (to fix issue rust-lang#70924) landed, I realized that I *could* make a local regression test, thanks to `rustc --print sysroot`: I can make a fresh "copy" (really mostly symlinks) of the sysroot, and then modify it to recreate the terms of this bug.

Fix codegen tests for RISC-V

Some codegen tests didn't seem relevant (e.g. unsupported annotations).

The RISC-V abi tests were broken by LLVM 10, c872dcf fixes that (cc: @msizanoen1)

I'm not sure about skipping catch-unwind.rs and included that change here mostly as a request for comment - I can't tell if that's a bug.

impl ToSocketAddrs for (String, u16)

This adds a convenience impl of `ToSocketAddrs for (String, u16)`. When authoring HTTP services it's common to take command line options for `host` and `port` and parse them into `String` and `u16` respectively. Consider the following program:
```rust
#[derive(Debug, StructOpt)]
struct Config {
    host: String,
    port: u16,
}

async fn main() -> io::Result<()> {
    let config = Config::from_args();
    let stream = TcpStream::connect((&*config.host, config.port))?; // &* is not ideal
    // ...
}
```

Networking is a pretty common starting point for people new to Rust, and seeing `&*` in basic examples can be confusing. Even as someone that has experience with networking in Rust I tend to forget that `String` can't be passed directly there. Instead with this patch we can omit the `&*` conversion and pass `host` directly:
```rust
#[derive(Debug, StructOpt)]
struct Config {
    host: String,
    port: u16,
}

async fn main() -> io::Result<()> {
    let config = Config::from_args();
    let stream = TcpStream::connect((config.host, config.port))?; // no more conversions!
    // ...
}
```

I think should be an easy and small ergonomics improvement for networking. Thanks!
