each of which is internally left-to-right:

This flag takes a FILTER argument and instructs the test runner to skip
the tests whose names contain the word FILTER. --skip can be used
several times.

---

My motivation for submitting this is that while using [smoke] to run `std` unit tests for cross
targets I found that a few of the tests always fail due to limitations in QEMU (it can't handle too
many threads) and I'd like to skip these problematic tests from the command line to be able to run
the rest of the unit tests.

[smoke]: https://github.com/japaric/smoke

I know there is another mechanism to skip tests: `#[ignore]` but this doesn't work in my use case
because I can't (easily) modify the source of the standard libraries to `#[ignore]` some tests. And
even if I could, the change would involve conditionally ignoring some tests for some targets but
that's not a perfect solution because those tests should pass if executed on real hardware so they
should not be `#[ignored]` in that scenario.

Previously, in cases where `EAI_SYSTEM` has been returned from getaddrinfo, the

Haiku: Initial work at OS support

These changes should be non-invasive to non-Haiku platforms. These patches were hand reworked from Neil's original Rust 1.9.0 patches. I've done some style cleanup and design updates along the way.

There are a few small additional patches to libc, rust-installer and compiler-rt that will be submitted once this one is accepted.

Haiku can be compiled on Linux, and a full gcc cross-compiler with a Haiku target is available, which means bootstrapping should be fairly easy. The patches here have already successfully bootstrapped under our haiku x86_gcc2 architecture. http://rust-on-haiku.com/wiki/PortingRust

I'll be focusing on our more modern gcc5 x86 and x86 architectures for now.

As for support, we're not seeking official support for now. We understand Haiku isn't a top-tier OS choice, however having these patches upstream greatly reduces the amount of patchwork we have to do. Mesa has Haiku code upstream, and we submit patches to keep it going. Mesa doesn't test on Haiku and we're ok with that :-)

Don't allocate during default HashSet creation.

The following `HashMap` creation functions don't allocate heap storage for elements.
```
HashMap::new()
HashMap::default()
HashMap::with_hasher()
```
This is good, because it's surprisingly common to create a HashMap and never
use it. So that case should be cheap.

However, `HashSet` does not have the same behaviour. The corresponding creation
functions *do* allocate heap storage for the default number of non-zero
elements (which is 32 slots for 29 elements).
```
HashMap::new()
HashMap::default()
HashMap::with_hasher()
```
This commit gives `HashSet` the same behaviour as `HashMap`, by simply calling
the corresponding `HashMap` functions (something `HashSet` already does for
`with_capacity` and `with_capacity_and_hasher`). It also reformats one existing
`HashSet` construction to use a consistent single-line format.

This speeds up rustc itself by 1.01--1.04x on most of the non-tiny
rustc-benchmarks.
