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
* 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.
In rustbuild itself we download from our mirror but in the containers we don't
do this yet. The OpenSSL download url changes from time to time (it breaks when
they release a new version) so let's download from our mirror instead.
Add disabled android host builders
Introduce the concept of disabled builder. A disabled builder is one that is not run by travis. It is intended to be run by the user who wants a rustc for a tier 2 or 3 platform. Off corse, there is no guarantee that it will work.
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.
LLVM 4.0 Upgrade
Since nobody has done this yet, I decided to get things started:
**Todo:**
* [x] push the relevant commits to `rust-lang/llvm` and `rust-lang/compiler-rt`
* [x] cleanup `.gitmodules`
* [x] Verify if there are any other commits from `rust-lang/llvm` which need backporting
* [x] Investigate / fix debuginfo ("`<optimized out>`") failures
* [x] Use correct emscripten version in docker image

Closes#37609.

**Test results:**
Everything is green 🎉
Add a comment for disabling errexit, try to debug appveyor cache
Comments added as requested.
Also, lets add some cache debugging to appveyor. I *think* this is how to ignore errors in cmd.exe (and I did try it on my own machine), but I'm not 100% sure how appveyor runs them. In the worst case it'll fail but I guess that isn't the end of the world since the build has already failed by this point.
r? @TimNN
This commit enables the `rust-analysis` package to be produced for all targets
that are part of the `dist-*` suite of docker images on Travis. Currently
these packages are showing up with `available = false` in the
`channel-rust-nightly.toml` manifest where we'd prefer to have them show up for
all targets.
Unfortunately rustup isn't handling the `available = false` section well right
now, so this should also inadvertently fix the nightly regression.
Add the RLS as a submodule and build a package out of it
r? @brson (and cc @alexcrichton) Please review closely, I am not at all convinced I've done the right things here. I did run `x.py dist` and it makes an rls package which looks right to my eyes, but I haven't tested on non-linux platforms nor am I really sure what it should look like.
This does not attempt to run tests for the RLS yet.
travis: Use upstream LLVM repositories for Fuchsia
The Fuchsia copies of LLVM repositories contain additional patches
for work-in-progress features and there is some amount of churn that
may break Rust. Use upstream LLVM repositories instead for building
the toolchain used by the Fuchsia builder.
dist-powerpc-linux: use a pure 32-bit CPU profile
With `-mcpu=power4`, code might use instructions like `fcfid`, excluding
older CPUs like the PowerPC G4, which apparently some users would like
to use. The generic `-mcpu=powerpc` should stick to pure 32-bit PowerPC
instructions.
Fixesrust-lang/cargo#3852.
Re-enable appveyor cache
After breaking the queue last time, I'm cautiously back with a PR to re-enable caching on appveyor.
If you look at https://ci.appveyor.com/project/rust-lang/rust/build/1.0.2623/job/46o90by4ari6gege (one of the multiple runs that started failed, there are actually two errors - one for restoring the cache, one right at the bottom for creating a directory. I only noticed the restore error at the time as I was a bit rushed to revert and didn't stop to wonder why it continued - turns out appveyor [does not abort on cache restore failure](https://github.com/appveyor/ci/issues/723).
Turns out the cause of the build failures was the cache directory existing and me being thinking that because mkdir on windows is [recursive by default](http://stackoverflow.com/a/905239/2352259), it ignores the error if the directory already exists. Apparently this is not true, so now it checks if the directory exists before attempting to create.
In addition, I've added some more paranoia to double check everything is sane.

I've tracked down what I believe is the last spurious sccache failure on #40240
to behavior in mio (carllerche/mio#583), and this commit updates the binaries to
a version which has that fix incorporated.
