Pursuant to issue #25663, this commit adds the max and min functions to the Ord trait, enabling items that implement Ord to use UFCS (ex. 1.max(2)) instead of the longer std::cmp::max(1,2) format.
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.

Create directory for dump-mir-dir automatically
Fixes#35543 r? @Mark-Simulacrum
@Mark-Simulacrum I know someone else said that they'll work on this, but it has been 3+ weeks and I had nothing to do and wanted to contribute a bit.
I now added the call to automatically create the directory as discussed, but was wondering how you feel about the suggestion to set a default directory, i.e. `target/mir`?

Change for-loop desugar to not borrow the iterator during the loop
This is enables the use of suspend points inside for-loops in movable generators. This is illegal in the current desugaring as `iter` is borrowed across the body.
Introduce 'run-pass' header to 'ui' tests in compiletest. Fix issue #36516.
<del>`ui-run` test is a combination of `ui` test and `run-pass` test. It is used to test lint output.</del>
Added support of `// run-pass` header to `ui` tests.
The compiler message of each test must match the corresponding `*.stderr` file like the traditional `ui` tests. Additionally, the compiled output must be executed successfully like the `run-pass` test.
12 `run-pass`/`run-pass-fulldeps` tests are moved to `ui`/`ui-fulldeps` plus the headers. After this move, no `run-pass`/`run-pass-fulldeps` tests should rely on the compiler's JSON message. This allows us to stop passing `--error-format json` in run-pass tests, thus fixing #36516.
array drop glue: avoid using out-of-bounds index lvalues
Avoid using out-of-bounds index lvalues. Miri doesn't like them, and they seem fishy in general.
Instead, use a pointer cast to compute the address of the beginning, and Offset to compute the end.

incr.comp.: Use DefPathHash-based DepNodes in the serialized DepGraph and remove obsolete DefIdDirectory
With this PR we don't store the dep-graph as a set of `DepNode<IndexIntoDefIdDirectory>` anymore but instead as a set of `DepNode<DefPathHash>`. Since a `DefPathHash` is a global identifier that is valid across compilation sessions, we don't need the `DefIdDirectory` anymore.
Since a `DepNode<DefPathHash>` is bigger than a `DepNode<IndexIntoDefIdDirectory>` and our on-disk encoding of the dep-graph is inefficient, this PR will probably increase the amount of space the dep-graph takes up on disk. I'm in the process of gathering some performance data.
The changes in here are a step towards implementing ICH-based `DepNodes` (#42294).

rustbuild: Remove RUSTFLAGS logic in rustc shim
This was added in #38072 but I can't recall why and AFAIK Cargo already handles
this. This was discovered through #42146 where passing duplicate flags was
causing problems.
Use callsite's span for macro calls on suggestion
When suggesting an appropriate mutability for a macro call, use the call
span instead of the expanded macro's span.

rustbuild: Add `./x.py test --no-fail-fast`
This option forwards to each `cargo test` invocation, and applies the
same logic across all test steps to keep going after failures. At the
end, a brief summary line reports how many commands failed, if any.
Note that if a test program fails to even start at all, or if an
auxiliary build command related to testing fails, these are still left
to stop everything right away.
Fixes#40219.
Reduce verbosity of build logs
This does two separate things.
- Sets sccache logging to warn instead of info.
- Makes tests when running for a given PR (not on auto branch) quiet. (cc @eddyb)
