Add conversions from File and Child* handles to Stdio
`Stdio` now implements `From<ChildStdin>`, `From<ChildStdout>`,
`From<ChildStderr>`, and `From<File>`.
The `Command::stdin`/`stdout`/`stderr` methods now take any type that
implements `Into<Stdio>`.
This makes it much easier to write shell-like command chains, piping to
one another and redirecting to and from files. Otherwise one would need
to use the unsafe and OS-specific `from_raw_fd` or `from_raw_handle`.

add playbot jokes to run-pass test
Some funny expressions that people pull out on IRC, that might actually be useful to test pathological parser behavior.
Skip documentation files without ``` when running markdown tests.
This should reduce the 'running 0 tests' noise in builds, and I believe this is a good heuristic for us to use.
cc @rust-lang/docs -- do we use the indented format for code blocks anywhere? Will we? If so, we shouldn't do this.

Always quote program name in Command::spawn on Windows
[`CreateProcess`](https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425.aspx) will interpret args as part of the binary name if it
doesn't find the binary using just the unquoted name. For example if
`foo.exe` doesn't exist, `Command::new("foo").arg("bar").spawn()` will
try to launch `foo bar.exe` which is clearly not desired.
Disallow underscore suffix for string-like literals.
This patch turns string/bytestring/char/byte literals followed by an underscore, like `"Foo"_`, to an error.
`scan_optional_raw_name` will parse `_` as a valid raw name, but it will be rejected by the parser. I also considered just stopping parsing when the suffix is `_`, but in that case `"Foo"_` will be lexed as two valid tokens.
Fixes the latter half of #41723.
[fuchsia] Track change of mx_job_default
The implementation of mx_job_default changed from a macro which
accessed the __magenta_job_default global variable to a proper
function call. This patch tracks that change.

Use tracked data introduced in #42196 to provide a better closure
error message by showing why a closure implements `FnOnce`.

Show trait method signature when impl differs
When the trait's span is available, it is already being used, add a
`note` for the cases where the span isn't available:
