279a780804 auto merge of #15983 : brson/rust/fail, r=alexcrichton
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!()
}
```

do_fail_empty before:

```
	leaq	8(%rsp), %rdi
	movabsq	$13, %rsi
	leaq	"str\"str\"(1494)"(%rip), %rax
	movq	%rax, 8(%rsp)
	movq	$19, 16(%rsp)
	callq	_ZN6unwind31begin_unwind_no_time_to_explain20h57030457935ab6111SdE@PLT

do_fail_fmt:

```
#[inline(never)]
fn do_fail_fmt() {
    fail!("guh{}", "faw")
}
```

do_fail_fmt before:

```

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.

Some minor changes to the compiler to expose this information. Very
inconvenient since struct fields aren't an item.

531a3c680d rustdoc: show struct field docs when inlined
Some minor changes to the compiler to expose this information. Very

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.
