6df66c194d auto merge of #7109 : bblum/rust/rwlocks, r=brson 
r? @brson

links to issues: #7065 the race that's fixed; #7066 the perf improvement I added. There are also some minor cleanup commits here.

To measure the performance improvement from replacing the exclusive with an atomic uint, I edited the ```msgsend-ring-rw-arcs``` bench test to do a ```write_downgrade``` instead of just a ```write```, so that it stressed the code paths that accessed ```read_count```. (At first I was still using ```write``` and saw no performance difference whatsoever, whoooops.)

The bench test measures how long it takes to send 1,000,000 messages by using rwarcs to emulate pipes. I also measured the performance difference imposed by the fix to the ```access_lock``` race (which involves taking an extra semaphore in the ```cond.wait()``` path). The net result is that fixing the race imposes a 4% to 5% slowdown, but doing the atomic uint optimization gives a 6% to 8% speedup.

Note that this speedup will be most visible in read- or downgrade-heavy workloads. If an RWARC's only users are writers, the optimization doesn't matter. All the same, I think this more than justifies the extra complexity I mentioned in #7066.

The raw numbers are:
```
with xadd read count
        before write_cond fix
                4.18 to 4.26 us/message
        with write_cond fix
                4.35 to 4.39 us/message
                
with exclusive read count
        before write_cond fix
                4.41 to 4.47 us/message
        with write_cond fix
                4.65 to 4.76 us/message
```

c7013ba1fc std::dynamic_lib: start fixing windows implementation 
The code compiles and runs under windows now, but I couldn't look up any
symbol from the current executable (dlopen(NULL)), and calling looked
up external function handles doesn't seem to work correctly under windows.

18542568a8 std: rename .connect/.concat in VectorVector to avoid conflicting with StrVector. 
This is caused by StrVector having a generic implementation for &[S]
and so #5898 means that method resolution of ~[~[1]].concat() sees that
both StrVector and VectorVector have methods that (superficially) match.

They are now connect_vec and concat_vec, which means that they can actually be
called.

073e82fff2 std: create Str trait for DRY. Use it on StrVector. 
The Str trait collects the various strings types and provides a method
for coercing to a slice, so that functions and impls can be written for
generic types containing strings (e.g. &[~str], &[&str], ...) without
having to write one for each string type (assuming that the impl only
needs a slice).

The confusing mixture of byte index and character count meant that every
use of .substr was incorrect; replaced by slice_chars which only uses
character indices. The old behaviour of `.substr(start, n)` can be emulated
via `.slice_from(start).slice_chars(0, n)`.

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);

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.

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
}

There were several old `#[doc(hidden)]` attributes in libstd and

definitions, tagged with `FIXME #3538`.

Since #3538 is now closed, I removed the `#[doc(hidden)]` attributes
as well as the FIXMEs, but I left `#[doc(hidden)]` in
libstd/task/spawn.rs and libstd/task/rt.rs since those two are
apparently `pub`, as well as in libextra/std.rc since std/extra is
`pub`.
