auto merge of #20432 : nikomatsakis/rust/fn-inference-2, r=eddyb
...
Previously, the borrow mode of each upvar was inferred as part of regionck. This PR moves it into its own separate step. It also employs the `ExprUseVisitor`, further simplifying the code. The eventual goal is to support better inference of `Fn` vs `FnMut` vs `FnOnce` that is not based on the expected type, as well as supporting individual by-move upvars.

Move upvar checking into its own pre-pass that occurs before regionck
...
and which uses EUV. For now, upvar inference is not any smarter than
it ever was, but regionck is simpler because it doesn't have to do as
many things at once.

Make ty::ParameterEnvironment, not ty::ctxt, implement Typer and
...
`UnboxedClosureTyper`. This requires adding a `tcx` field to
`ParameterEnvironment` but generally simplifies everything since we
only need to pass along an `UnboxedClosureTyper` or `Typer`.

NB. Some of the hunks in this commit rely on a later commit which adds
`tcx` into `param_env` and modifies `ParameterEnvironment` to
implement `Typer`.

Re-introduce McResult<> as a way of aborting mem-categorization (and

expr-use-visitor) early. Turns out I was wrong to remove this; it
causes a lot of pain trying to run EUV etc during typeck without
ICEing on erroneous programs.

auto merge of #20154 : P1start/rust/qualified-assoc-type-generics, r=nikomatsakis
...
This modifies `Parser::eat_lt` to always split up `<<`s, instead of doing so only when a lifetime name followed or the `force` parameter (now removed) was `true`. This is because `Foo<<TYPE` is now a valid start to a type, whereas previously only `Foo<<LIFETIME` was valid.
This is a [breaking-change]. Change code that looks like this:
```rust
let x = foo as bar << 13;
```
to use parentheses, like this:
```rust
let x = (foo as bar) << 13;
```
Closes #17362 .

auto merge of #19835 : pythonesque/rust/add-unordered-intrinsic, r=thestinger
...
This corresponds to the JMM memory model's non-volatile reads and writes to shared variables. It provides fairly weak guarantees, but prevents UB (specifically, you will never see a value that was not written _at some point_ to the provided location). It is not part of the C++ memory model and is only legal to provide to LLVM for loads and stores (not fences, atomicrmw, etc.).
Valid uses of this ordering are things like racy counters where you don't care about the operation actually being atomic, just want to avoid UB. It cannot be used for synchronization without additional memory barriers since unordered loads and stores may be reordered freely by the optimizer (this is the main way it differs from relaxed).
Because it is new to Rust and it provides so few guarantees, for now only the intrinsic is provided--this patch doesn't add it to any of the higher-level atomic wrappers.

Travis recently launched their new infrastructure on Amazon EC2 with improved resources. The only limitation is that they don't support sudo. http://blog.travis-ci.com/2014-12-17-faster-builds-with-container-based-infrastructure/
I couldn't find anywhere where the build system uses sudo so I don't think that limitation affects rust builds.
This change drops the current `make tidy` times [slightly](https://travis-ci.org/daramos/rust/builds )(travis-test branch).
