#37653 support `default impl` for specialization
this commit implements the first step of the `default impl` feature:
> all items in a `default impl` are (implicitly) `default` and hence
> specializable.
In order to test this feature I've copied all the tests provided for the
`default` method implementation (in run-pass/specialization and
compile-fail/specialization directories) and moved the `default` keyword
from the item to the impl.

Shrink the rust-src component
Before this change, the installable rust-src component had essentially the same contents as the rustc-src dist tarball, just additionally wrapped in a rust-installer. As discussed on [internals], rust-src is only meant to support uses for the standard library, so it doesn't really need the rest of the compiler sources.
Now rust-src only contains libstd and its path dependencies, which roughly matches the set of crates that have rust-analysis data. The result is **significantly** smaller, from 36MB to 1.3MB compressed, and from 247MB to 8.5MB uncompressed.
Rollup merge of #41524 - michaelwu:basic-hexagon, r=alexcrichton
Add Hexagon support
This requires an updated LLVM with https://reviews.llvm.org/D31999 and https://reviews.llvm.org/D32000 to build libcore.
A basic hello world builds and runs successfully on the hexagon simulator. libcore is fine with LLVM fixes, but libstd requires a lot more work since there's a custom rtos running on most hexagon cores. Running Linux sounds possible though, so maybe getting linux + musl going would be easier.
Here's the target file I've been using for testing

Make sure openssl compiles with only one core
This is (hopefully) a fix for the osx openssl spurious failure - #40417.
The intermittent failures and failing in different ways made me think of a race condition. But programs are parallel make safe right? [Not openssl](https://github.com/openssl/openssl/issues/298). But we don't do a parallel make on openssl [do we](https://github.com/rust-lang/rust/blob/8c4f2c64c6759a82f143e23964a46a65c67509c9/src/bootstrap/native.rs#L309)? This confused me, except "Waiting for unfinished jobs" is present in the logs...which is evidence of a parallel make!
It turns out that when we invoke to top level target [in run.sh](https://github.com/rust-lang/rust/blob/036983201d4e9aeb5c5e56e47c305971972b2569/src/ci/run.sh#L75-L77), make will [pass the flags downwards](https://www.gnu.org/software/make/manual/html_node/Options_002fRecursion.html) in order to take advantage of parallelism in sub-makes. Of course, we don't want this in openssl! Override this by explicitly disabling parallelism on the command line.
I don't know why this hasn't happened on anything except OSX. Maybe Linux binutils check if the file is in use?

appveyor: Upgrade to gcc for mingw 6.3.0
This commit sort of brings back #40777 by upgrading back to 6.3.0. While
investigating #40546 it was discovered that 6.3.0 appears to not spurious
fail in the same way that 6.2.0 does (which we're currently using). The
workaround for #40184 contained in #40777 did not work so this commit also
contains a different workaround for the gdb issue. We will not download the
6.2.0 version of gdb and use that instead of the default version that comes with
6.3.0.

Support AddressSanitizer and ThreadSanitizer on x86_64-apple-darwin
[ASan](https://clang.llvm.org/docs/AddressSanitizer.html#supported-platforms) and [TSan](https://clang.llvm.org/docs/ThreadSanitizer.html#supported-platforms) 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/` (due to https://reviews.llvm.org/D6018), so the user needs to additionally pass `-C rpath`:~~
Auto merge of #41504 - eddyb:query-api, r=nikomatsakis
Improve the librustc on-demand/query API ergonomics.
Queries are now performed through these two forms:
* `tcx.type_of(def_id)` (the most common usage)
* `tcx.at(span).type_of(def_id)` (to provide a more specific location in the cycle stack)
Several queries were renamed to work better as method names, i.e. by suffixing with `_of`.
Auto merge of #41258 - clarcharr:str_box_extras, r=Kimundi
More methods for str boxes. (reduce Box<[u8]> ↔ Box<str> transmutes)
This is a follow-up to #41096 that adds safer methods for converting between `Box<str>` and `Box<[u8]>`. They're gated under a different feature from the `&mut str` methods because they may be too niche to include in public APIs, although having them internally helps reduce the number of transmutes the standard library uses.
What's added:
* `From<Box<str>> for Box<[u8]>`
* `<Box<str>>::into_boxed_bytes` (just calls `Into::into`)
* `alloc::str` (new module)
* `from_boxed_utf8` and `from_boxed_utf8_unchecked`, defined in `alloc:str`, exported in `collections::str`
* exports `from_utf8_mut` in `collections::str` (missed from previous PR)

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
