Looks like Travis [has announced][blog] that our current `xcode8.2` image is
being deprecated and the recommended Xcode 7 image is `xcode7.3`. This updates
us to these ahead of time to make sure we can shake out any bugs, if any.

ci: Upload/download from a new S3 bucket
Moving buckets from us-east-1 to us-west-1 because us-west-1 is where
rust-central-station itself runs and in general is where we have all our other
buckets.
ci: Disable rustc debug assertions on OSX
This commit disables debug assertions for OSX in an effort to improve cycle time
on OSX. It looks like #44610 didn't shave off quite as much time as desired so
let's see how much this helps.

Make use of Travis's conditional jobs.
Conditional jobs: https://docs.travis-ci.com/user/conditional-builds-stages-jobs/#Conditional-Jobs.
Jobs not matching the condition will not be scheduled at all. This allows us to get rid of `$ALLOW_PR`/`$ALLOW_TRY`/`$SKIP_BUILD` in `.travis.yml`, and perfectly prevent spurious PR failures due to flaky macOS machines.
travis: Move sccache to the us-west-1 region
Most of the other rust-lang buckets are in us-west-1 and I think the original
bucket was just accidentally created in the us-east-1 region. Let's consolidate
by moving it to the same location as the rest of our buckets.

Our OSX builders are routinely and significantly over hour 2 hour "soft limit"
for testing PRs. I *think* that a big portion of this time comes from the fact
that LLVM and debug assertions are enabled. In an effort to speed up these
builders and reduce cycle time this commit disables LLVM assertions on OSX for
all builders.
My thinking is that we'll let this bake for a bit after merged to see what the
effect is on timing on Travis. If it doesn't actually help much we can turn them
back on, and if it doesn't help enough we can disable Rust debug assertions as
well.

Fix sanitizer tests on buggy kernels
Travis recently pushed an update to the Linux environments, namely the kernels
that we're running on. This in turn caused some of the sanitizer tests we run to
fail. We also apparently weren't the first to hit these failures! Detailed in
google/sanitizers#837 these tests were failing due to a specific commit in the
kernel which has since been backed out, but for now work around the buggy kernel
that's deployed on Travis and eventually we should be able to remove these
flags.

Reorder the job matrix to take advantage of the order how Travis CI starts
them in rust-lang/rust. Plus other refactoring of `.travis.yml`.
1. Move the `$ALLOW_PR` image to the top, so users' PRs will start testing
immediately. Previously the `$ALLOW_PR` image starts 6 minutes after the
build was scheduled.
2. Move the slow macOS images near the top, so they share more time with
the rest of the faster Linux builds, which should shorten total test
time (actually not much, about 7 minutes at most if this change does
work).
3. Merged the `install` section of both Linux and macOS to make the `env:`
section a bit shorter, and enable change 4 below.
4. Do not download or install anything if `$SKIP_BUILD == true`, which
further reduces chance of spurious failure in the PR-CI stage (avoid the
red cross appearing even if CI passed).
Use the `-f` flag to indicate that, for example, a 500 response code is to be
considered a failure, triggering the normal retry logic. Also ignore errors
where we check the date from google.com, as a failure there shouldn't fail the
build.
Add a travis builder for wasm32-unknown-emscripten
This commits add an entry to travis matrix that will execute wasm32-unknown-emscripten tests suites.
- Emscripten for asmjs was updated to sdk-1.37.13-64bit
- The tests are run with node 8.0.0 (it can execute wasm)
- A wrapper script is used to run each test from the directory where it is (workaround for https://github.com/kripken/emscripten/issues/4542)
- Some tests are ignore, see #42629 and #42630
Build instruction profiler runtime as part of compiler-rt
r? @alexcrichton
This is #38608 with some fixes.
Still missing:
- [x] testing with profiler enabled on some builders (on which ones? Should I add the option to some of the already existing configurations, or create a new configuration?);
- [x] enabling distribution (on which builders?);
- [x] documentation.
There is no `minimal` language. Due to travis-ci/travis-ci#4895, it will
fallback to `ruby`, which certainly isn't what we want. `generic` is an
undocumented (travis-ci/docs-travis-ci-com#910) language that serves the
desired purpose.
* Bring back colors on Travis, which was disabled since #39036.
Append --color=always to cargo when running in CI environment.
* Removed `set -x` in the shell scripts. The `retry` function already
prints which command it is running, add `-x` just add noise to the
output.
* Support travis_fold/travis_time. Matching pairs of these allow Travis CI
to collapse the output in between. This greatly cut down the unnecessary
"successful" output one need to scroll through before finding the failed
statement.
Generate XZ-compressed tarballs
Integrate the new `rust-installer` and extend manifests with keys for xz-compressed tarballs.
One of the steps required for https://github.com/rust-lang/rust/issues/21724
Now that the final bug fixes have been merged into sccache we can start
leveraging sccache on the MSVC builders on AppVeyor instead of relying on the
ad-hoc caching strategy of trigger files and whatnot.
ASan and TSan are supported on macOS, and this commit enables their
support.
The sanitizers are always built as *.dylib on Apple platforms, so they
cannot be statically linked into the corresponding `rustc_?san.rlib`. The
dylibs are directly copied to `lib/rustlib/x86_64-apple-darwin/lib/`
instead.
Note, although Xcode also ships with their own copies of ASan/TSan dylibs,
we cannot use them due to version mismatch.
There is a caveat: the sanitizer libraries are linked as @rpath, so the
user needs to additionally pass `-C rpath`:
rustc -Z sanitizer=address -C rpath file.rs
^~~~~~~~
Otherwise there will be a runtime error:
dyld: Library not loaded: @rpath/libclang_rt.asan_osx_dynamic.dylib
Referenced from: /path/to/executable
Reason: image not found
Abort trap: 6
The next commit includes a temporary change in compiler to force the linker
to emit a usable @rpath.
