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.

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

Document use of `compiler_builtins` with `no_std` binaries
See discussion in #43264.
The docs for the `compiler_builtins_lib` feature were removed in
PR #42899. But, though the `compiler_builtins` library has been
migrated out-of-tree, the language feature remains, and is needed to
use the stand-alone crate. So, we reintroduce the docs for the
feature, and add a reference to them when describing how to create a
`no_std` executable.
Rework Rustbuild to an eagerly compiling approach
This introduces a new dependency on `serde`; I don't believe that's a problem since bootstrap is compiled with nightly/beta always so proc macros are available. Compile times are slightly longer -- about 2-3x (30 seconds vs. 10 seconds). I don't think this is too big a problem, especially since recompiling bootstrap is somewhat rare. I think we can remove the dependency on Serde if necessary, though, so let me know.

Tidy: allow common lang+lib features
This allows changes to the Rust language that have both library
and language components share one feature gate.
The feature gates need to be "about the same change", so that both
library and language components must either be both unstable, or
both stable, and share the tracking issue.
Removes the ugly "proc_macro" exception added by #40939.
Closes#43089
Update the `cargo` submodule
Notably pull in an update to the `jobserver` crate to have Cargo set the
`CARGO_MAKEFLAGS` environment variable instead of the `MAKEFLAGS` environment
variable.

Switch to rust-lang-nursery/compiler-builtins
This commit migrates the in-tree `libcompiler_builtins` to the upstream version
at https://github.com/rust-lang-nursery/compiler-builtins. The upstream version
has a number of intrinsics written in Rust and serves as an in-progress rewrite
of compiler-rt into Rust. Additionally it also contains all the existing
intrinsics defined in `libcompiler_builtins` for 128-bit integers.
It's been the intention since the beginning to make this transition but
previously it just lacked the manpower to get done. As this PR likely shows it
wasn't a trivial integration! Some highlight changes are:
* The PR rust-lang-nursery/compiler-builtins#166 contains a number of fixes
across platforms and also some refactorings to make the intrinsics easier to
read. The additional testing added there also fixed a number of integration
issues when pulling the repository into this tree.
* LTO with the compiler-builtins crate was fixed to link in the entire crate
after the LTO process as these intrinsics are excluded from LTO.
* Treatment of hidden symbols was updated as previously the
`#![compiler_builtins]` crate would mark all symbol *imports* as hidden
whereas it was only intended to mark *exports* as hidden.

fixed some clippy warnings in compiletest
This is mainly readability stuff. Whenever the `clone_ref` lint asked me to clone the dereferenced object, I removed the `.clone()` instead, relying on the fact that it has worked so far and the immutable borrow ensures that the value won't change.
add `allow_fail` test attribute
This change allows the user to add an `#[allow_fail]` attribute to
tests that will cause the test to compile & run, but if the test fails
it will not cause the entire test run to fail. The test output will
show the failure, but in yellow instead of red, and also indicate that
it was an allowed failure.
Here is an example of the output: http://imgur.com/a/wt7ga
