We'd previously assumed that these paths would be relative to the src
dir, and that for example our various CI scripts would, when calling
x.py, use `../x.py build ../src/tools/...` but this isn't the case --
they use `../x.py` without using the relevant source-relative path.
We eventually may want to make this (actually somewhat logical) change,
but this is not that time.
Primarily for CI purposes; this is intended to avoid cases where we
update rustbuild and unintentionally make CI stop running some builds to
the arguments being passed no longer applying for some reason.
Implement excluding a build-step via --exclude
First step to fixing https://github.com/rust-lang/rust/issues/47911. This doesn't change any CI configuration, but implements what I believe necessary to make that feasible in rustbuild.
In theory this should be sufficient to allow someone to open a PR against .travis.yml and appveyor.yml which splits the Windows 32-bit tests and maybe the OS X tests into multiple builders (depending on what our cost-concerns are) to reduce runtimes.

Some Steps are by-default run but don't have any paths associated with
them. We need to have at least one PathSet per each Step, though, so we
add an empty one on calls to `never()`.
Previously, a Step would be able to tell on its own when it was invoked
"by-default" (that is, `./x.py test` was called instead of `./x.py test
some/path`). This commit replaces that functionality, invoking each Step
with each of the paths it has specified as "should be invoked by."
For example, if a step calls `path("src/tools/cargo")` and
`path("src/doc/cargo")` then it's make_run will be called twice, with
"src/tools/cargo" and "src/doc/cargo." This makes it so that default
handling logic is in builder, instead of spread across various Steps.
However, this meant that some Step specifications needed to be updated,
since for example `rustdoc` can be built by `./x.py build
src/librustdoc` or `./x.py build src/tools/rustdoc`. A `PathSet`
abstraction is added that handles this: now, each Step can not only list
`path(...)` but also `paths(&[a, b, ...])` which will make it so that we
don't invoke it with each of the individual paths, instead invoking it
with the first path in the list (though this shouldn't be depended on).
Future work likely consists of implementing a better/easier way for a
given Step to work with "any" crate in-tree, especially those that want
to run tests, build, or check crates in the std, test, or rustc crate
trees. Currently this is rather painful to do as most of the logic is
duplicated across should_run and make_run. It seems likely this can be
abstracted away into builder somehow.
rustbuild: Pass `ccache` to build scripts
Right now the ccache setting is only used for LLVM, but this tweaks it to also
be used for build scripts so C++ builds like `librustc_llvm` can be a bit
speedier.

Dist builds should always be as fast as we can make them, and since
those run on CI we don't care quite as much for the build being somewhat
slower. As such, we don't automatically enable ThinLTO on builds for the
dist builders.
Right now this directory is located under:
$sysroot/lib/rustlib/$target/lib/codegen-backends
but after seeing what we do in a few other places it seems that a more
appropriate location would be:
$sysroot/lib/rustlib/$target/codegen-backends
so this commit moves it!
This currently only supports a limited subset of the full compilation,
but is likely 90% of what people will want and is possible without
building a full compiler (i.e., running LLVM). In theory, this means
that contributors who don't want to build LLVM now have an easy way to
compile locally, though running tests won't work.
Test rustdoc js
Add tests for the rustdoc search. It was heavily required because of all the recent breaking changes that happened while I went through improvements in doc search (add search in/for generic search for example).
* Bump the release version to 1.25
* Bump the bootstrap compiler to the recent beta
* Allow using unstable rustdoc features on beta - this fix has been applied to
the beta branch but needed to go to the master branch as well.
Run the miri test suite on the aux builder and travis
Reopen of #38350
see https://github.com/rust-lang/rust/pull/43340#issuecomment-316940762 for earlier discussion
Rationale for running miri's test suite in rustc's CI is that miri currently contains many features that we want in const eval in the future, and these features would break if the test suite is not run.

rustbuild: Don't pass `-j` if called by `make`
In these situations Cargo just prints out a warning about ignoring the flag
anyway, so let `make` take care of jobs and whatnot instead of getting warnings
printed.

Doc tests are temporarily disabled until next release cycle, since
current beta Cargo errors on them. Upgrade should be smooth as the
relevant tests are already fixed in this commit.
Add clippy as a submodule
~~This builds clippy as part of `./x.py build` (locally and in CI).~~
This allows building clippy with `./x.py build src/tools/clippy`
~~Needs https://github.com/nrc/dev-tools-team/issues/18#issuecomment-322456461 to be resolved before it can be merged.~~ Contributers can simply open a PR to clippy and point the submodule at the `pull/$pr_number/head` branch.
This does **not** build clippy or test the clippy test suite at all as per https://github.com/nrc/dev-tools-team/issues/18#issuecomment-321411418

This controls the value of the crt-static feature used when building the
standard library for a target, as well as the compiler itself when that
target is the host.
As discussed in

This is a redirect meant to be replaced once cargo docs have been
converted to mdbook. We just want *a* URL to ride the trains for now so
that we can print doc.rust-lang.org/cargo in the paper book and
guarantee that it will go *somewhere* useful by the time the book is
printed.
Implemented as a meta redirect in HTML because we don't currently have
any google juice at doc.rust-lang.org/cargo to lose.
