add links for Box, Rc, and Vec

remove extra `../`s

I can no longer find these methods in nightly docs.

Previously we didn't normalize the function signatures used for
closures. This didn't cause a problem in most cases, but caused an ICE
in during MIR type checking.

Fixes rust-lang#36139

Currently it checks only the first argument.

Fixes rust-lang#31216

We've got tests which require a particular version of LLVM to run as they're
testing bug fixes. Our build system, however, supports multiple LLVM versions,
so we can't run these tests on all LLVM versions.

This adds a new `min-llvm-version` directive for tests so they can opt out of
being run on older versions of LLVM. This then namely applies that logic to the
`issue-36023.rs` test case and...

Add `must_use` to the Reference

I'm a bit uncertain about the exact phrasing, but having it mentioned at all is probably better than before.

Document try!'s error conversion behaviour

try!'s documentation currently doesn't document the error conversion behaviour of the macro. This patch extends the documentation.

Open questions:
* is it worthwhile to have seperate examples with and without wrapping behaviour? It's not immediately obvious that From<T> for T is always defined. Though this is necessary for the macro to work in any case, is this the place to expect that knowledge.

Normalize the function signature of closures

Update lifetime errors to specifically note temporaries

This PR updates the error message we give in the case of a temporary value not living long enough.

Before:

Now:

<img width="488" alt="screen shot 2016-08-31 at 10 03 01 am" src="https://cloud.githubusercontent.com/assets/547158/18138557/2e5cf322-6f62-11e6-9047-4a78abf3d78c.png">

Specifically, it makes the following changes:

* Detects if a temporary is being used.  If so, it changes the labels to mention that a temporary value specifically is in question
* Simplifies wording of the existing labels to focus on lifetimes rather than values being valid
* Changes the help to a note, since the help+span wasn't as helpful (and sometimes more confusing) than just a note.

Special case a few colors for Windows

As brought up on [this thread](rust-lang#33240 (comment)) the colors used in error messages on Windows can be difficult to read because of the lack of bold.

This PR makes a few changes to improve readability, namely:
* Rather than using BRIGHT_BLUE, on Windows we now use BRIGHT_CYAN, which is easier to read on black when you do not have bold
* We used BRIGHT_YELLOW rather than YELLOW, for the same reason
* Titles will be BRIGHT_WHITE now, to give the illusion of being bold

Some examples:

Fixed E0529's label and unit test

Fixes rust-lang#36195 part of rust-lang#35233.

This is ready for review, but will likely fail Travis due to rust-lang#36138. I changed the wording of the label, so feedback on that would be appreciated.
