Looks like Travis [has announced][blog] that our current `xcode8.2` image is
being deprecated and the recommended Xcode 7 image is `xcode7.3`. This updates
us to these ahead of time to make sure we can shake out any bugs, if any.

Add "Buidling on *nix" sub-header
Since there is a "Build on Windows" section, a simple sub-header here would help Windows users to know they need to keep reading.
Check namespaces when resolving associated items in typeck
Closes#35600Closes#44247
Fixes a "cannot move a value of type..." error in the same case as #44247 but with the associated items swapped.
rustc: Remove `used_mut_nodes` from `TyCtxt`
This updates the borrowck query to return a result, and this result is then used
to incrementally check for unused mutable nodes given sets of all the used
mutable nodes.
Closes#42384
While an inner attribute here is in fact erroneous, that error ("inner
attribute is not permitted in this context") successfully gets set earlier;
this further admonition is nonsensical.
Resolves#45296.
rustbuild: Support specifying archiver and linker explicitly
With this patch `x.py test` passes without toolchain being in `PATH` if `cc`, `cxx`, `ar`, `linker` and `gdb` are specified in `config.toml` (except for a few `run-make` tests using `nm`).

rustc: Fix some ThinLTO internalization
First the `addPreservedGUID` function forgot to take care of "alias" summaries.
I'm not 100% sure what this is but the current code now matches upstream. Next
the `computeDeadSymbols` return value wasn't actually being used, but it needed
to be used! Together these should...
Closes#45195
There was a bit of code shared between `try_get_with` and `ensure`, after I
added `ensure`. I refactored that shared code into a query-agnostic method
called `read_node_index`.
The new method `read_node_index` will attempt to find the node
index (`DepNodeIndex`) of a query. When `read_node_index` finds the
`DepNodeIndex`, it marks the current query as a reader of the node it's
requesting the index of.
This is used by `try_get_with` and `ensure` as it elides the unimportant (to
them) details of if the query is invalidated by previous changed computation (Red)
or new and if they had to mark the query green. For both `try_get_with` and
`ensure`, they just need to know if they can lookup the results or have to
reevaluate.
some low-hanging rustdoc optimizations
There were a few discussions earlier today in #rust-internals about the syscall usage and overall performance of rustdoc. This PR is intended to pick some low-hanging fruit and try to rein in some of the performance issues of rustdoc.
First the `addPreservedGUID` function forgot to take care of "alias" summaries.
I'm not 100% sure what this is but the current code now matches upstream. Next

incr.comp.: Introduce `ensure` and `ensure` typeck_tables_of
Resolves#45210
In this Pull Request we introduce the `ensure` query/function. `ensure` has the
semantics and type of the function `Q1` below:
```rust
fn Q1::ensure(K){
Q(K);
}
```
Further, `ensure` avoids the need to load the result from disk (or execute the
provider, if we are not storing the results of Q to disk).
@nikomatsakis
Provide the full span of method calls to `check_argument_types`
... so that it includes the span of the passed arguments, not just the name of the called method.
Fixes#44760.
Fix TcpStream::connect_timeout on linux
Linux appears to set POLLOUT when a conection's refused, which is pretty
weird. Invert the check to look for an error explicitly. Also add an
explict test for this case.
Closes#45265.

Do some cleanups for hashmaps
@mystor noticed some things whilst reading through the hashmap RawTable code.
Firstly, in RawTable we deal with this hash_offset value that is the offset of the list of hashes from the buffer start. This is always zero, and this isn't consistently used (which means that we would have bugs if we set it to something else). We should just remove this since it doesn't help us at all.
Secondly, the probing length tag is not copied when cloning a raw table. This is minor and basically means we do a bit more work than we need on further inserts on a cloned hashmap.

compiletest/runtest: format ErrorKind with Display
The strings are nouns for the most part, so we give ErrorKind::Help a
more sensible string. This reduces quote hiccups in failure output.

Add x86_64-unknown-linux-gnux32 target
This adds X32 ABI support for Linux on X86_64. Let's package and dist it so we can star testing libc, libstd, etc.
Fixes https://github.com/rust-lang/rfcs/issues/1339
doc-test: In Markdown tests, Use all of `<h1>` to `<h6>` as the test name
This mainly simplifies debugging error index tests, as the error codes are `<h2>`s in the huge document containing all codes.
Linux appears to set POLLOUT when a conection's refused, which is pretty
weird. Invert the check to look for an error explicitly. Also add an
explict test for this case.

Enable building clippy in CI
r? @alexcrichton
As discussed at Rustfest. Measured additional time is 4 minutes on my machine if no dependencies are shared with other tools. In reality most dependencies are shared (especially the slow to compile ones like serde).
cc @Manishearth
Does not run clippy's test suite, since
a) it is nontrivial in the rustc build system
b) it breaks more frequently but the breakage is negligible
If clippy breaks, the procedure to follow is documented under https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#external-dependencies
This updates the borrowck query to return a result, and this result is then used
to incrementally check for unused mutable nodes given sets of all the used
mutable nodes.
