53e8bd641a auto merge of #19449 : nikomatsakis/rust/unboxed-closure-fn-impl, r=pcwalton 
Implement the `Fn` trait for bare fn pointers in the compiler rather
than doing it using hard-coded impls. This means that it works also
for more complex fn types involving bound regions.

3c89031e1f auto merge of #18613 : steveklabnik/rust/ownership_guide, r=huonw 
This is a work in progress, but this should get *extensive* review, so I'm putting it up early and often.

This is the start of a draft of the new 'ownership guide,' which explains ownership, borrowing, etc. I'm feeling better about this framing than last time's, but we'll see.

207a508411 auto merge of #18770 : pczarn/rust/hash_map-explicit-shrinking, r=Gankro 
Part of enforcing capacity-related conventions, for #18424, the collections reform.

Implements `fn shrink_to_fit` for HashMap.
The `reserve` method now takes as an argument the *extra* space to reserve.

daa0745886 auto merge of #18749 : nikomatsakis/rust/builtin-bounds-like-other-traits, r=pcwalton 
Treat builtin bounds like all other kinds of trait matches. Introduce a simple hashset in the fulfillment context to catch cases where we register the exact same obligation twice. This helps prevent duplicate error reports but also handles the recursive obligations created by builtin bounds.

594e21f19b Correct various compile-fail tests. Most of the changes are because we 
now don't print duplicate errors within one context, so I sometimes
had to break functions into two functions.

2b35e6fa08 auto merge of #19357 : michaelwoerister/rust/fix-issue-18791, r=alexcrichton 
One negative side-effect of this change is that there might be quite a bit of copying strings out of the codemap, i.e. one copy for every block that gets translated, just for taking a look at the last character of the block. If this turns out to cause a performance problem then `CodeMap::span_to_snippet()` could be changed return `Option<&str>` instead of `Option<String>`.

Fixes #18791

de95ad4c46 auto merge of #19436 : lifthrasiir/rust/rustdoc-short-src-paths, r=alexcrichton 
Before: `doc/src/collections/home/lifthrasiir/git/rust/src/libcollections/vec.rs.html`
After: `doc/src/collections/vec.rs.html`

If the source code is in the parent dirs relative to the crate root, `..` is replaced with `up` as expected. Any other error like non-UTF-8 paths or drive-relative paths falls back to the absolute path.

There might be a way to improve on false negatives, but this alone should be enough for fixing #18370.

I.e. we should not prematurely build operand constraints at the expansion time. Otherwise `--pretty expanded` diverges:

```
$ cat t.rs
#![feature(asm)]

pub fn main() { unsafe { asm!("" : : : "hello", "world") }; }

$ rustc t.rs --pretty
#![feature(asm)]

pub fn main() { unsafe { asm!("" : : : "hello" , "world") }; }

$ rustc t.rs --pretty expanded
#![feature(asm)]
#![feature(phase)]
#![no_std]
#![feature(globs)]
#[phase(plugin, link)]
extern crate "std" as std;
#[prelude_import]
use std::prelude::*;

pub fn main() { unsafe { asm!("":  :  : "~{hello},~{world}") }; }
```

(The last code *does* compile, but won't do the expected thing.)

    impl Foo for Bar {
        extern "C" unsafe fn foo() { ... }

Change such code to look like this:

    trait Foo {

    }

    impl Foo for Bar {
        unsafe extern "C" fn foo() { ... }
