14c331053e auto merge of #6815 : kballard/rust/hashmap-insert_or_modify_with, r=erickt 
`std::hashmap::HashMap.insert_or_update_with()` is basically the opposite
of `find_or_insert_with()`. It inserts a given key-value pair if the key
does not already exist, or replaces the existing value with the output
of the passed function if it does.

This is useful because replicating this with existing functionality is awkward, especially with the current borrow-checker. In my own project I have code that looks like

	if match map.find_mut(&key) {
		None => { true }
		Some(x) => { *x += 1; false }
	} {
		map.insert(key, 0);
	}

and it took several iterations to make it look this good. The new function turns this into

    map.insert_or_update_with(key, 0, |_,x| *x += 1);

7bc950c43c Refactor some hashmap code into a new private function mangle() 
Add new private hashmap function

    fn mangle(&mut self,
              k: K,
              not_found: &fn(&K) -> V,
              found: &fn(&K, &mut V)) -> uint

Rewrite find_or_insert() and find_or_insert_with() on top of mangle().

Also take the opportunity to change the return type of find_or_insert()
and find_or_insert_with() to &'a mut V. This fixes #6394.

Closes #5090 by using the excellent new generic deriving code

Promotes the unreachable code attribute to a lint attribute (instead of always being a warning)

Fixes some edge cases when creating hashmaps/hashsets and also when consuming them. (fixes #5998)

35655a0fb3 auto merge of #6803 : Thiez/rust/native_fmax_fmin, r=brson 
Calls to the libc versions of fmin and fmax were relatively slow (perhaps because they could not be inlined?). This pull request provides f32 and f64 with fmin and fmax written in Rust, and shows a significant speed increase on my system; I used https://github.com/thiez/rustray as my benchmark, with --opt-level 3 it brings the ray-tracing time down from 10.8 seconds to about 9.2, which seemed significant to me.

24784e8030 auto merge of #6771 : thestinger/rust/highlight, r=luqmana 
This works with pandoc linked against highlighting-kate >= 0.5.3.8. It seems to just be a no-op with earlier versions, because I successfully ran this through `try`.

This also fixes some consistency issues (like making `Example`/`Examples` always a header and always using three tildes).

dbc57584bd auto merge of #6724 : thestinger/rust/swap_fast, r=thestinger 
Passing higher alignment values gives the optimization passes more freedom since it can copy in larger chunks. This change results in rustc outputting the same post-optimization IR as clang for swaps and most copies excluding the lack of information about padding.

Code snippet:

```rust
#[inline(never)]
fn swap<T>(x: &mut T, y: &mut T) {
    util::swap(x, y);
}
```

Original IR (for `int`):

```llvm
define internal fastcc void @_ZN9swap_283417_a71830ca3ed2d65d3_00E(i64*, i64*) #1 {
static_allocas:
  %2 = icmp eq i64* %0, %1
  br i1 %2, label %_ZN4util9swap_283717_a71830ca3ed2d65d3_00E.exit, label %3

; <label>:3                                       ; preds = %static_allocas
  %4 = load i64* %0, align 1
  %5 = load i64* %1, align 1
  store i64 %5, i64* %0, align 1
  store i64 %4, i64* %1, align 1
  br label %_ZN4util9swap_283717_a71830ca3ed2d65d3_00E.exit

_ZN4util9swap_283717_a71830ca3ed2d65d3_00E.exit:  ; preds = %3, %static_allocas
  ret void
}
```

After #6710:

```llvm
define internal fastcc void @_ZN9swap_283017_a71830ca3ed2d65d3_00E(i64* nocapture, i64* nocapture) #1 {
static_allocas:
  %2 = load i64* %0, align 1
  %3 = load i64* %1, align 1
  store i64 %3, i64* %0, align 1
  store i64 %2, i64* %1, align 1
  ret void
}
```

After this change:

```llvm
define internal fastcc void @_ZN9swap_283017_a71830ca3ed2d65d3_00E(i64* nocapture, i64* nocapture) #1 {
static_allocas:
  %2 = load i64* %0, align 8
  %3 = load i64* %1, align 8
  store i64 %3, i64* %0, align 8
  store i64 %2, i64* %1, align 8
  ret void
}
```

Another example:

```rust
#[inline(never)]
fn set<T>(x: &mut T, y: T) {
    *x = y;
}
```

Before, with `(int, int)` (align 1):

```llvm
define internal fastcc void @_ZN8set_282517_8fa972e3f9e451983_00E({ i64, i64 }* nocapture, { i64, i64 }* nocapture) #1 {
static_allocas:
  %2 = bitcast { i64, i64 }* %1 to i8*
  %3 = bitcast { i64, i64 }* %0 to i8*
  tail call void @llvm.memcpy.p0i8.p0i8.i64(i8* %3, i8* %2, i64 16, i32 1, i1 false)
  ret void
}
```

After, with `(int, int)` (align 8):

```llvm
define internal fastcc void @_ZN8set_282617_8fa972e3f9e451983_00E({ i64, i64 }* nocapture, { i64, i64 }* nocapture) #1 {
static_allocas:
  %2 = bitcast { i64, i64 }* %1 to i8*
  %3 = bitcast { i64, i64 }* %0 to i8*
  tail call void @llvm.memcpy.p0i8.p0i8.i64(i8* %3, i8* %2, i64 16, i32 8, i1 false)
  ret void
}
```
