In theory we shouldn't require trusty so long as docker continues to
work!

Actually run compiletest tests on CI
I was assuming that https://github.com/rust-lang/rust/pull/56792 would
have resulted in compiletest tests being executed on CI. However, I
couldn't find any mentions of the unit test names in any CI logs.
This adds the compiletest test execution to the checktools.sh script.

rustc: Update Clang used to build LLVM on Linux
This commit updates from LLVM 7.0.0 to git revisions of clang/llvm/lld
to build LLVM on our dist builders for Linux. The goal of this is to
fix #56849 by picking up a fix [1] in LLD.
Closes #56849
[1]: https://github.com/llvm-mirror/lld/commit/3be4e82db78b46a8ca349b2b799dec620a6f159f

This way, checktools.sh continues to be used only for tools that are
published later on.

Add targets thumbv7neon-linux-androideabi and thumbv7neon-unknown-linux-gnueabihf
These two targets enable both thumb-mode and NEON for ARMv7 CPUs.
This another attempt at #49902, which cannot be reopened. Between that PR and this one, some subrepos with C code whose build systems were failing went away.

Bump minimum required LLVM version to 6.0
Based on the discussion in #55842, while the overall position of Rust wrt LLVM continues to be contentious, there does seem to be a consensus that there is no need for continued support of LLVM 5. This PR bumps our version requirement to LLVM 6.0 and makes Travis run against that.
I hope that this is going to unblock #52694. If I understand correctly, while this issue still exists in LLVM 6, Ubuntu has backported the relevant patch.

This builder is not really the correct place to put this, but it
definitely has the time budget and checking this tool builds on just one
platform is more than sufficient.

The run-pass test suite currently takes 30 minutes on Windows, and
that appears to be roughly split between two 15 minute runs of the test
suite: one without NLL and one with NLL. In discussion on Discord the
platform coverage of the NLL compare mode may not necessarily be worth
it, so this commit removes the NLL compare mode from tests by default,
and then reenables it on only one builder.

Hopefully will speed up CI slightly!

This commit deletes the `alloc_system` crate from the standard
distribution. This unstable crate is no longer needed in the modern
stable global allocator world, but rather its functionality is folded
directly into the standard library. The standard library was already the
only stable location to access this crate, and as a result this should
not affect any stable code.

Update emscripten
This updates emscripten to 1.38.15, which is based on LLVM 6.0.1 and would allow us to drop code for handling LLVM 4.
The main issue I ran into is that exporting statics through `EXPORTED_FUNCTIONS` no longer works. As far as I understand exporting non-functions doesn't really make sense under emscripten anyway, so I've modified the symbol export code to not even try.
Closes #52323.

[CI] Run a `thumbv7m-none-eabi` binary using `qemu-system-arm` [IRR-2018-embedded]
## What's included?
- Run a `thumbv7m-none-eabi` binary using `qemu-system-arm`
- We are using `cortex-m-rt = "=0.5.4"` which does not use `proc_macro`.
(reason: stage2 build of rustc does not work well with `proc_macro` in `run-make` phase.)
- We are using GNU LD for now.
## Blocker
All resolved.
- ~[Waiting] `#[panic_handler]` is not available in stable.~
- [Merged] https://github.com/rust-lang/rust/pull/53619
- ~[Waiting] https://github.com/japaric/lm3s6965evb: does not compile on stable.~
- [OK] dependent crate ~`panic-abort`~ `panic-halt`: already moved to use `#[panic_handler]`.
## Update
`#[panic_handler]` will be stabilized in Rust 1.30.

ci: Add Dockerfile for dist-powerpcspe-linux
This adds the Dockerfile for cross-building Rust for the powerpcspe target. It's currently disabled.

Use lld directly for Fuchsia target
Fuchsia already uses lld as the default linker, so there's no reason
to always invoke it through Clang, instead we can simply invoke lld
directly and pass the set of flags that matches Clang.

This commit adds opt-in support to the compiler to link to `jemalloc` in
the compiler. When activated the compiler will depend on `jemalloc-sys`,
instruct jemalloc to unprefix its symbols, and then link to it. The
feature is activated by default on Linux/OSX compilers for x86_64/i686
platforms, and it's not enabled anywhere else for now. We may be able to
opt-in other platforms in the future! Also note that the opt-in only
happens on CI, it's otherwise unconditionally turned off by default.
Closes #36963

Bug #52452 notes some debuginfo test regressions when moving to gdb
8.1. This series will also cause versions of gdb before 8.2 to fail
when a recent LLVM is used -- DW_TAG_variant_part support was not
added until 8.2.
This patch updates one of the builders to a later version of Ubuntu,
which comes with gdb 8.2. It updates the relevant tests to require
both a new-enough LLVM and a new-enough gdb; the subsequent patch
arranges to continue testing the fallback mode.
The "gdbg" results are removed from these tests because the tests now
require a rust-enabled gdb.
If you read closely, you'll see that some of the lldb results in this
patch still look a bit strange. This will be addressed in a
subsequent patch; I believe the fix is to disable the Python
pretty-printers when lldb is rust-enabled.

In addition to to updating Cargo's submodule and Cargo's dependencies,
this also updates Cargo's build to build OpenSSL statically into Cargo
as well as libcurl unconditionally. This removes OpenSSL build logic
from the bootstrap code, and otherwise requests that even on OSX we
build curl statically.

* Make it influence the behavior of the compiled rustc, rather than
just the rustc build system. That is, if verify_llvm_ir=true,
even manual invocations of the built rustc will verify LLVM IR.
* Enable verification of LLVM IR in CI, for non-deploy and
deploy-alt builds. This is similar to how LLVM assertions are
handled.

This commit updates the debuginfo that is encoded in all of our released
artifacts by default. Currently it has paths like `/checkout/src/...` but these
are a little inconsistent and have changed over time. This commit instead
attempts to actually define the file paths in our debuginfo to be consistent
between releases.
All debuginfo paths are now intended to be `/rustc/$sha` where `$sha` is the git
sha of the released compiler. Sub-paths are all paths into the git repo at that
`$sha`.

[experimental]: Build LLVM with ThinLTO enabled (2nd attempt)
This is https://github.com/rust-lang/rust/pull/51207 revived. This time, I'd like to run actual performance tests to see if it improves compile times.

Similar to `armebv7r-none-eabihf`, but for Little-endian MCUs.
As example TI RM4x/RM5x are Little-endian Cortex-R4F/R5F MCUs.
CI/Dockerfile is intentionally in the disabled folder.

Align 6-week cycle check with beta promotion instead of stable release.
The regression check is to make beta promotion easier, so it makes more
sense to use the Tuesday of the release week (T-2) as the end point of the
regression prevention, instead of Thursday (T-0). But since the beta
promotion PR is sent at Tuesday evening at UTC, the protection should
include the whole Tuesday as well, meaning the 6-week cycle will start from
Wednesdays.
This will also move the start of the regression protection week one day
earlier.
