The majority of this change is modifying some of the `ast_visit` methods to return multiple values.
It's prohibitively expensive to allocate a `~[Foo]` every time a statement, declaration, item, etc is visited, especially since the vast majority will have 0 or 1 elements. I've added a `SmallVector` class that avoids allocation in the 0 and 1 element cases to take care of that.
It turns out that libuv was returning ENOSPC to us in our usage of the
uv_ipX_name functions. It also turns out that there may be an off-by-one in
libuv. For now just add one to the buffer size and handle the return value
correctly.
Closes#10663

This moves the locking/waiting methods to returning an RAII struct instead of
relying on closures. Additionally, this changes the methods to all take
'&mut self' to discourage recursive locking. The new method to block is to call
`wait` on the returned RAII structure instead of calling it on the lock itself
(this enforces that the lock is held).
At the same time, this improves the Mutex interface a bit by allowing
destruction of non-initialized members and by allowing construction of an empty
mutex (nothing initialized inside).
This PR removes almost all `_iter` suffixes in various APIs of the codebase that return Iterators, as discussed in #9440.
As a summarize for the intend behind this PR:
- Iterators are the recommended way to provide a potentially lazy list of values, no need to name them painfully verbose. If anything, functions that return a specific container type should have more verbose names.
- We have a static type system, so no need to encode the return value of a constructor function into its name.
Following is a possibly incomplete list of all renamings I performed in the codebase. For a few of them I'm a bit unsure whether the new name still properly expresses their functionality, so feedback would be welcome:

I'm also planning a few more changes, like removing all unnecessary `_rev` constructors (#9391), or reducing the `split` variants on `&str` to a more versatile and concise system.
This patchset fixes some parts broken on Win64.
This also adds `--disable-pthreads` flags to llvm on mingw-w64 archs (both 32-bit and 64-bit, not mingw) due to bad performance. See #8996 for discussion.
This patchset makes warning if crate-level attribute is used at other places, obsolete attributed is used, or unknown attribute is used, since they are usually from mistakes.
Closes#3348
This is needed so that the FFI works as expected on platforms that don't
flatten aggregates the way the AMD64 ABI does, especially for `#[repr(C)]`.
This moves more of `type_of` into `trans::adt`, because the type might
or might not be an LLVM struct.
Closes#10308.
