Add run-pass case for issue #14308

Enum wildcard patterns in match behave wrong when applied to tuple
structs. They either ICE or cause an LLVM error.
Fix ICE regarding tuple struct matches using (..)

Fixes half of #14308.
Fix LLVM error with tuple struct match using (..)

Consider PatEnums constructed with A(..) to be candidates for tuple
struct patterns, not just ones constructed with A(a,b,c). If these
patterns shouldn't be valid tuple struct patterns (as they're equivalent
to _), this needs to be caught before we get to trans.

Fixes #14308.
std: Change hash to reexport its own Writer

One of the long-term goals of the libstd facade is to move the collections
library underneath the standard library. This would imply that libcollections
today would invert its dependency with libstd.

One of the primary blockers for doing this is the HashMap collection. Of its two
major dependencies, hashing and randomness, this commit is the first step in
dealing with hashing.

When moving the hash module beneath libstd, it must break its primary dependence
on the io::Writer trait (used as the hashing state). The proposed strategy for
breaking this dependence is taking a similar path as core::fmt, which is to have
the hash module define its own "writer trait". This trait would be similar to
std::io::Writer, except that it would not return errors and it would have fewer
convenience methods.

The Hash trait today has its type parameter behind a feature gate (default type
parameters), so this pending change will likely break no code which hasn't opted
in to the feature gate. The SipState struct will lose its implementation of
io::Writer, but it will regain similar methods for dealing with writing data.

This change specifically prepares for the hash migration by modifying
deriving(Hash) to use the std::hash::Writer bound instead of the std::io::Writer
bound. This bound is currently wired to std::io::Writer, but after a snapshot it
will have no need to be wired to the io writer trait.
Add examples for edge cases of str.split/str.splitn

In particular, show examples for splitting the empty string and using `splitn`
with a count of 0.

Fix #14222.
migrate from `exchange_malloc` to `allocate`

This is now only used internally by the compiler.
alter `exchange_free` for sized deallocation

The support for sized deallocation is nearly complete. The only known
missing pieces are `Box<str>`, `Box<[T]>` and `proc`.
rustdoc: Show types for traits across crates

Right now, when you look in the "Implementors" section for traits, you only see
implementors within that crate. This commit modifies that section to include
implementors from neighboring crates as well.

For example, the Container trait currently says that it is only implemented by
strings and slices, but it is in fact implemented by nearly all containers.

Implementation-wise, this change generates an "implementors cache" similarly to
the search index where each crate will append implementors to the files. When
the page for a trait is loaded, it will load its specific cache file, rendering
links for all upstream types which implement the trait.
Change static.rust-lang.org to doc.rust-lang.org

The new documentation site has shorter urls, gzip'd content, and index.html
redirecting functionality.

Add a suggestion to use a `let` binding on some borrowck errors.

Spelling/doc formatting fixes.
syntax: put the correct span on doc-comments inside a module.

The position of the .bump call (before extracting the span fields) was
causing a doc-comment to have the span of the next token, not itself.
