Fixed a typo in the documentation of std::mem, and refactored a function to use match instead of if.
Also added a FIXME to the benchmarks at the end of the file stating that they should be moved to another place, because they have nothing to do with `mem` (see https://github.com/mozilla/rust/issues/13642)
When a uv_tcp_t is closed in libuv, it will still invoke the pending connect_cb,
and I thought that it would always call it with ECANCELED, but it turns out that
sometimes we'll get a different error code instead. Handle this case by checking
to see if the request's data is NULL and bail out if so (the timeout expired).
Refactores all uses of ty_vec and associated things to remove the vstore abstraction (still used for strings, for now). Pointers to vectors are stored as ty_rptr or ty_uniq wrapped around a ty_vec. There are no user-facing changes. Existing behaviour is preserved by special-casing many instances of pointers containing vectors. Hopefully with DST most of these hacks will go away. For now it is useful to leave them hanging around rather than abstracting them into a method or something.
Closes#13554.
LruEntry nodes previously used Option to encapsulate the key and value
fields. This was used merely as a way avoid having values for the sigil
node. Apart from wasting a few bytes for the discriminant, this
cluttered the rest of the code, since these fields always contained
Some on regular nodes as a class invariant.
The Option wrapping was removed, and the values in the sigil field are
initialized using mem::init, so that they don't contain any real data.
Instead of passing through CC which may have things like ccache and other
arguments (when using clang) this commit filters out the necessary arguments
from CC to pass the right linker to rustc.

In upgrading LLVM, only rust functions had the "split-stack" attribute added.
This commit changes the addition of LLVM's "split-stack" attribute to *always*
occur and then we remove it sometimes if the "no_split_stack" rust attribute is
present.

Previously, symbols with rust escape sequences (denoted with dollar signs)
weren't demangled if the escape sequence showed up in the middle. This alters
the printing loop to look through the entire string for dollar characters.
This adds a `TcpStream::connect_timeout` function in order to assist opening
connections with a timeout (cc #13523). There isn't really much design space for
this specific operation (unlike timing out normal blocking reads/writes), so I
am fairly confident that this is the correct interface for this function.
The function is marked #[experimental] because it takes a u64 timeout argument,
and the u64 type is likely to change in the future.

On windows, correctly check for errors when spawning threads, and on both
windows and unix handle the error more gracefully rather than printing an opaque

Make all of the methods in `std::num::Float` take `self` and their other parameters by value.
Some of the `Float` methods took their parameters by value, and others took them by reference. This standardises them to one convention. The `Float` trait is intended for the built in IEEE 754 numbers only so we don't have to worry about the trait serving types of larger sizes.
[breaking-change]
Move the rounding functions into the `std::num::Float` trait and then remove `std::num::Round`.
This continues the flattening of the numeric traits tracked in #10387. The aim is to make `std::num` very simple and tied to the built in types, leaving the definition of more complex numeric towers to third-party libraries.

This is a bit of an interesting upgrade to LLVM. Upstream LLVM has started using C++11 features, so they require a C++11 compiler to build. I've updated all the bots to have a C++11 compiler, and they appear to be building LLVM successfully:
* Linux bots - I added gcc/g++ 4.7 (good enough)
* Android bots - same as the linux ones
* Mac bots - I installed the most recent command line tools for Lion which gives us clang 3.2, but LLVM wouldn't build unless it was explicitly asked to link to `libc++` instead of `libstdc++`. This involved tweaking `mklldeps.py` and the `configure` script to get things to work out
* Windows bots - mingw-w64 has gcc 4.8.1 which is sufficient for building LLVM (hurray!)
* BSD bots - I updated FreeBSD to 10.0 which brought with it a relevant version of clang.
The largest fallout I've seen so far is that the test suite doesn't work at all on FreeBSD 10. We've already stopped gating on FreeBSD due to #13427 (we used to be on freebsd 9), so I don't think this puts us in too bad of a situation. I will continue to attempt to fix FreeBSD and the breakage on there.
The LLVM update brings with it all of the recently upstreamed LLVM patches. We only have one local patch now which is just an optimization, and isn't required to use upstream LLVM. I want to maintain compatibility with LLVM 3.3 and 3.4 while we can, and this upgrade is keeping us up to date with the 3.5 release. Once 3.5 is release we will in theory no longer require a bundled LLVM.
When calling a function, or anything with nested parens,
default to cindent's indent. The least error-prone way I
could think of identifying this is to look for a line
that ends with a ',', as well as a non-zero number of
any character except parens before the comma, and
then an open paren.
This will overlap with the previous rule accounting for
function definitions, but that should be fine because
it is also using cindent.
Configure required git be installed so this should be added to the dependencies list. If it's only required when using git, a note could also be added.
