c8c3579bff Fix closure arguments which are immediate because of field reordering.
While building immediates goes through type_of::type_of, extracting them must account for field reorderings.

cf5f80c68d Fix having multiple reprs on the same type.
This bug has applied to master for an indefinite period of time and is orthogonal to univariant layout optimization.

Fix travis builds

After reading some articles [1] [2] yesterday about Docker and the "init"
process I got to thinking about the problems that we've been seeing on Travis.
The basic problem is that a Linux system may need an "init" process to work
properly when processes become zombies. Docker by default doesn't handle this
and the root process typically isn't an init process, so this can occasionally
cause quite a few problems.

We've been seeing spurious errors on Travis inside containers which look like
OOM and such, but my guess is that zombie processes were being reparented to the
top-level shell. The shell didn't expect the zombies and then behaved very
strangely.

This commit fixes these problems by using Yelp's "dumb-init" program [2] as the
init process in all of our containers. This ensures that there's a valid init
ready to reap children when they're reparented, which our test suite apparently
generates a bunch of throughout the tests and such.

aa7a2e9e61 Auto merge of #38181 - jsgf:test-filter-exact, r=alexcrichton
libtest: add --exact to make filter matching exact

Filter matching is by substring by default. This makes it impossible
to run a single test if its name is a substring of some other test.
For example, its not possible to run just `mymod::test` with these
tests:

```
  mymod::test
  mymod::test1
  mymod::test_module::moretests
```

You could declare by convention that no test has a name that's a
substring of another test, but that's not really practical.

This PR adds the `--exact` flag, to make filter matching exactly
match the complete name.

bbf2b70893 rustbuild: Skip some more non-relevant dist steps
This commit skips a few more dist tragets during compilation which shouldn't be
necessary.

* First, when packaging std we only take action when the host target is the
  build target. Otherwise we package the same artifacts a number of times, which
  shouldn't be necessary.
* Next, we apply the same logic to the save-analysis build. This is actually
  required for correctness as the build compiler is the only one which actually
  has save analysis information. This should fix an error seen on nightlies.

a1f5001998 rustc: Use create_dir_racy in save analysis
The OSX bots failed last night due a race condition in save analysis where
concurrent calls to `fs::create_dir_all` conflicted with one another. This
replaces the relevant function call with `fs::create_dir_racy` which is defined
internally to the compiler.

b1a2ab86db Auto merge of #38179 - michael-zapata:rf/harmonise_rustdoc_errors, r=GuillaumeGomez
feat(rustdoc): harmonise error messages

Based on unix tools wording, it follows a standard format: `program_name: context: error message`, potentially prompting the user to use the `--help` option.

This is clearly meant to trigger some discussion on #38084, as messages still use `stdout` and `stderr` somewhat arbitrarily, and there are a few `error!()` calls as well.

4e696edc71 rustbuild: Add cli option --keep-stage
This option is intended to be used like:

./x.py build --stage 1 --keep-stage 0

Which skips all stage 0 steps, so that stage 1 can be recompiled
directly (even if for example libcore has changes).

This is useful when working on `cfg(not(stage0))` parts of the
libraries, or when re-running stage 1 tests in libraries in general.
