Move time out of extra (cc #8784)
Add Pod trait bound to std::num::Primitive
Decouple integer formatting from std::num::strconv

This works towards a complete rewrite and ultimate removal of the `std::num::strconv` module (see #6220), and the removal of the `ToStrRadix` trait in favour of using the `std::fmt` functionality directly. This should make for a cleaner API, encourage less allocation, and make the implementation far more comprehensible.

The `Formatter::pad_integral` method has also been refactored make it easier to understand.

The formatting tests for integers have been moved out of `run-pass/ifmt.rs` in order to provide more immediate feedback when building using `make check-stage2-std NO_REBUILD=1`.

The benchmarks have been standardised between std::num::strconv and std::num::fmt to make it easier to compare the performance of the different implementations.

Arbitrary radixes are now easier to use in format strings. For example:

~~~
assert_eq!(format!("{:04}", radix(3, 2)), ~"0011");
~~~
Reduce reliance on `to_str_radix`

This is in preparation to remove the implementations of ToStrRadix in integers, and to remove the associated logic from `std::num::strconv`.

The parts that still need to be liberated are:

- `std::fmt::Formatter::runplural`
- `num::{bigint, complex, rational}`

More work towards finishing #8784.

I was reading the code and saw this. Not the best contribution of my life ;-).
auto merge of #12422 : alexcrichton/rust/buffered-default, r=brson

One of the most common ways to use the stdin stream is to read it line by line
for a small program. In order to facilitate this common usage pattern, this
commit changes the stdin() function to return a BufferedReader by default. A new
`stdin_raw()` method was added to get access to the raw unbuffered stream.

I have not changed the stdout or stderr methods because they are currently
unable to flush in their destructor, but #12403 should have just fixed that.
Restore LLVM to the correct revision

auto merge of #12437 : alexcrichton/rust/travis-yml, r=brson

Travis CI provides an easy-to-use continuous integration infrastructure for
github repos to use. Travis will automatically test all PRs which are opened
against the rust repository, informing PR owners of the test results.

I believe that this will be a very convenient piece of infrastructure as we'll
be able to reduce the load on bors quite a bit. In theory all PRs opened have
had the full test suite run against them, but unfortunately this is rarely the
case (I'm a prime suspect). Travis will be able to provide easy and relatively
quick (~30min) feedback for PRs. By ensuring fewer failures on bors, we can
hopefully feed more successful jobs to bors.

Overall, I expect this to be very helpful for new contributors as well as
regular contributors as it's another layer of tests being run which will
hopefully catch things sooner. One of the most convenient parts about using
Travis is that there's very little burden in terms of maintenance, and if things
go wrong we can easily turn travis completely off.

Note that this is *not* the metric by which a PR will be merged with. Using
travis will purely be another source for running tests, we will continue to gate
all PRs on bors.

Not all of those messages are covered by tests. I am not sure how to trigger them and where to put those tests.

Also some message patterns in the existing tests are not complete.
For example, i find `error: mismatched types: expected "i32" but found "char" (expected i32 but found char)` a bit repetitive, but as i can see there is no test covering that.
