We previously reexported entire modules, which caused private things to
become reachable and trip the dead code and private items in public API
lints.

Closes #15912

f653d9f9bf auto merge of #16033 : nham/rust/hash_tuple_impl, r=alexcrichton 
Previously the implementation of Hash was limited to tuples of up to arity 8. This increases it to tuples of up to arity 12. 

Also, the implementation macro for `Hash` used to expand to something like this:

    impl Hash for (a7,)
    impl Hash for (a6, a7)
    impl Hash for (a5, a6, a7)
    ...

This style is inconsistent with the implementations in core::tuple, which look like this:

    impl Trait for (A,)
    impl Trait for (A, B)
    impl Trait for (A, B, C)
    ...

This is perhaps a minor point, but it does mean the documentation pages are inconsistent. Compare the tuple implementations in the documentation for [Hash](http://static.rust-lang.org/doc/master/std/hash/trait.Hash.html) and [PartialOrd](http://static.rust-lang.org/doc/master/core/cmp/trait.PartialOrd.html)

This changes the Hash implementation to be consistent with `core::tuple`.

A few refactorings to decrease text size and increase data size. I'm not sure about this tradeoff. Various stats below. cc @pcwalton

This reduces the code needed to pass arguments for `fail!()`, `fail!("{}", ...)`, and to a lesser extent `fail!("...")`. Still more work to be done on compiler-generated failures and the `fail!("...")` case.

do_fail_empty:

```
#[inline(never)]
fn do_fail_empty() {
    fail!()
}
```

File size increases.

Text size decreases by 52486 while data size increases by 143686.

I don't know if anything can be learned from these benchmarks. Looks like a wash.

Stumbled across this and thought it would be cool to prove. I've never used Ogden's Lemma before, but I'm pretty sure I used it right. The pumping lemma definitely doesn't seem sufficient for the job. In particular, when using the pumping lemma, you can always just pump one of the quotes, and it's fine. Ogden's Lemma lets you effectively force the pumper to use certain characters in the string.

This commit applies stability attributes to the contents of these modules,
summarized here:

* The `unit` and `bool` modules have become #[unstable] as they are purely meant
  for documentation purposes and are candidates for removal.

* The `ty` module has been deprecated, and the inner `Unsafe` type has been
  renamed to `UnsafeCell` and moved to the `cell` module. The `marker1` field
  has been removed as the compiler now always infers `UnsafeCell` to be
  invariant. The `new` method i stable, but the `value` field, `get` and
  `unwrap` methods are all unstable.

* The `tuple` module has its name as stable, the naming of the `TupleN` traits
  as stable while the methods are all #[unstable]. The other impls in the module
  have appropriate stability for the corresponding trait.

* The `arc` module has received the exact same treatment as the `rc` module
  previously did.

* The `any` module has its name as stable. The `Any` trait is also stable, with
  a new private supertrait which now contains the `get_type_id` method. This is
  to make the method a private implementation detail rather than a public-facing
  detail.

  The two extension traits in the module are marked #[unstable] as they will not
  be necessary with DST. The `is` method is #[stable], the as_{mut,ref} methods
  have been renamed to downcast_{mut,ref} and are #[unstable].

  The extension trait `BoxAny` has been clarified as to why it is unstable as it
  will not be necessary with DST.

This is a breaking change because the `marker1` field was removed from the
`UnsafeCell` type. To deal with this change, you can simply delete the field and
only specify the value of the `data` field in static initializers.

7aa407958b auto merge of #15998 : luqmana/rust/nmnnbd, r=thestinger 
LLVM recently added a new attribute, dereferenceable: http://reviews.llvm.org/D4449

>This patch adds a dereferencable attribute. In some sense, this is a companion to the nonnull attribute, but specifies that the pointer is known to be dereferencable in the same sense as a pointer generated by alloca is known to be dereferencable.

With rust, everywhere that we previously marked `nonnull` we can actually mark as `dereferenceable` (which implies nonnull) since we know the size. That is, except for one case: when generating calls for TyVisitor. It seems like we haven't substituted the self type (so we have `ty_param`) and just treat it as an opaque pointer so I just left that bit as nonnull.

With this, LLVM can for example hoist a load out of a loop where it previously couldn't:

```Rust
pub fn baz(c: &uint, n: uint) -> uint {
    let mut res = 0;
    for i in range(0, n) {
        if i > 0 {
            res += *c * i;
        }
    }
    res
}
```

Before:
```llvm
define i64 @baz(i64* noalias nocapture nonnull readonly, i64) unnamed_addr #0 {
entry-block:
  br label %for_loopback.outer

for_loopback.outer:                               ; preds = %then-block-33-, %entry-block
  %.ph = phi i64 [ %.lcssa, %then-block-33- ], [ 0, %entry-block ]
  %res.0.ph = phi i64 [ %8, %then-block-33- ], [ 0, %entry-block ]
  br label %for_loopback

for_exit:                                         ; preds = %for_loopback
  %res.0.ph.lcssa = phi i64 [ %res.0.ph, %for_loopback ]
  ret i64 %res.0.ph.lcssa

for_loopback:                                     ; preds = %for_loopback.outer, %for_body
  %2 = phi i64 [ %4, %for_body ], [ %.ph, %for_loopback.outer ]
  %3 = icmp ult i64 %2, %1
  br i1 %3, label %for_body, label %for_exit

for_body:                                         ; preds = %for_loopback
  %4 = add i64 %2, 1
  %5 = icmp eq i64 %2, 0
  br i1 %5, label %for_loopback, label %then-block-33-

then-block-33-:                                   ; preds = %for_body
  %.lcssa = phi i64 [ %4, %for_body ]
  %.lcssa15 = phi i64 [ %2, %for_body ]
  %6 = load i64* %0, align 8                     ; <------- this load
  %7 = mul i64 %6, %.lcssa15
  %8 = add i64 %7, %res.0.ph
  br label %for_loopback.outer
}
```

After:
```llvm
define i64 @baz(i64* noalias nocapture readonly dereferenceable(8), i64) unnamed_addr #0 {
entry-block:
  %2 = load i64* %0, align 8                    ; <------- load once instead
  br label %for_loopback.outer

  %.ph = phi i64 [ %.lcssa, %then-block-33- ], [ 0, %entry-block ]
  %res.0.ph = phi i64 [ %8, %then-block-33- ], [ 0, %entry-block ]
  br label %for_loopback

for_exit:                                         ; preds = %for_loopback
  %res.0.ph.lcssa = phi i64 [ %res.0.ph, %for_loopback ]
  ret i64 %res.0.ph.lcssa

for_loopback:                                     ; preds = %for_loopback.outer, %for_body
  %3 = phi i64 [ %5, %for_body ], [ %.ph, %for_loopback.outer ]
  %4 = icmp ult i64 %3, %1
  br i1 %4, label %for_body, label %for_exit

for_body:                                         ; preds = %for_loopback
  %5 = add i64 %3, 1
  %6 = icmp eq i64 %3, 0
  br i1 %6, label %for_loopback, label %then-block-33-
