Avoid implying that any copyrights have been assigned to a separate
entity (such as "The Rust Project Developers") Rust contributors retain

Remove the inaccurate notice, and provide a clear explanation. Avoid
stating that all files contain copyright notices and/or license notices,

In the process, this also drops a separate notice that implies only some

Stabilize more APIs for the 1.20.0 release
In addition to the few stabilizations that have already landed, this cleans up the remaining APIs that are in `final-comment-period` right now to be stable by the 1.20.0 release
Make compiletest set cwd before running js tests
Proposed fix for #38800.
Not all tests pass yet - I will mention failures here once the test suite has finished.
Update RLS
This pulls in 79d659e569 It should fix#43453. It increases the timeout for test runs and forces builds in RLS tests to happen sequentially, this prevents interference between env vars passed to Cargo or rustc.

Constrain the layout of Blake2bCtx for proper SPARC compilation
On SPARC, optimization fuel ends up emitting incorrect load and store
instructions for the transmute() call in blake2b_compress(). If we
force Blake2bCtx to be repr(C), the problem disappears.
Fixes#43346
Fix printing regions with -Z verbose
When dumping MIR with `-Z verbose`, it would print regions on types, but not in the code. It seems the Rvalue printing code tried to be smart and guessed when the `Display` for `Region` would not possibly print anything.
This PR makes it no longer be smart, and just always use the `Display` like all the other code (e.g. printing types) does.
add a note to Vec's Extend<&T> impl about its slice specialization
From the regular documentation view, it's not at all apparent that [this specialization](5669c9988f/src/liballoc/vec.rs (L1879-L1891)) exists for `slice::Iter`. This adds a documentation blurb to the Extend impl itself to note that this optimization exists.
Point at path segment on module not found

Fix#43040.
Make the "main" constructors of NonZero/Shared/Unique return Option
Per discussion in https://github.com/rust-lang/rust/issues/27730#issuecomment-303939441.
This is a breaking change to unstable APIs.
The old behavior is still available under the name `new_unchecked`. Note that only that one can be `const fn`, since `if` is currently not allowed in constant contexts.
In the case of `NonZero` this requires adding a new `is_zero` method to the `Zeroable` trait. I mildly dislike this, but it’s not much worse than having a `Zeroable` trait in the first place. `Zeroable` and `NonZero` are both unstable, this can be reworked later.

doesn't exist.

Add a disabled builder for aarch64 emulated tests
This commit adds a disabled builder which will run all tests for the standard
library for aarch64 in a QEMU instance. Once we get enough capacity to run this
on Travis this can be used to boost our platform coverage of AArch64
bootstrap: Add doctests and unitests
This commit includes the following changes:
* Include more docstrings in classes, methods, and functions
* Add doctests, which are great for self-documenting our source code
* Add some unit tests with the `unittest` module
* Remove `WindowsError` reference on non-windows systems
* Rename some variables to be more explicit about their meaning
* Move all the attributes defined outside of `__init__`
* Add initial support for Python 3

Fixes#43346
Error message now makes clear that mutable borrow conflicts on a single
value in a loop body is caused by the borrow outlasting a single pass of
the loop.
Loop conflicts are detected by seeing when two borrow locations are the
same - which indicates the same code being run more than once.
Bump master to 1.21.0
This commit bumps the master branch's version to 1.21.0 and also updates the
bootstrap compiler from the freshly minted beta release.
This commit includes the following:
* Fix syntax errors in Python 3
* Include more docstrings in classes, methods, and functions
* Include unit tests using `unittest`
* Merge implementation of `{rustc,cargo}_out_of_date`
* Merge implementation of `RustBuild.{cargo,rustc}`
* Remove unnecessary source code
* Move all the attributes defined outside of `__init__`
* Remove remaining `%s` from print function
* Remove `WindowsError` reference on non-windows systems
* Rename some variables to be more explicit avoid their meaning
* Run bootstrap tests in the CI process
* Remove non-pythonic getters
* Remove duplicate code in `download_stage0` method
* Reduce the number of branches in `build_bootstrap` method
* Re-raise exception when we cannot execute uname in non-windows systems
* Avoid long lines
rustbuild: Fix the --build argument to bootstrap.py
This makes the --build argument also apply for the downloading of the stage0 toolchain and building rustbuild.
Fixes#42116
improve the TryFrom implementations
This removes the need for a 128 bit storage by making use of the fact that there can be either no over/underflow, either one or both, and each time the target type suffices to hold the limit for comparison. This also means that the implementation will work in targets without 128bit support (unless it's for 128bit types, of course).
The downside is that the code looks a bit more complex.
