Installed Rust 0.6 using Kevin Catu's PPA. REPL crashes on simplest inputs:

$ rust sketch

auto merge of #6467 : alexcrichton/rust/better-rusti, r=bstrie

These few commits address a few existing issues:

* #5469 - adding regression tests for `rusti`. This adds unit tests to the `rusti.rc` file (which needed some reorganization of the Makefile, see the first commit message). These are super-simple right now, and sadly can't test the output of the tests. I worked for a bit on making a compiletest version of the rusti tests, but I ended up hitting something which blocked me, although I've forgotten it by this point.
* #5937 - regression test added, and it's fixed
* #5803 - just doesn't appear to happen any more
* #5784 - it's no longer broken, and it no longer spits out warnings about unused variables.

I also did some investigation into #5774, and you may want to read the comment I left on the bug. The gist of the situation is that C++ exceptions across JIT code don't look like they're working, even though they [should be working](https://github.com/mozilla/rust/blob/3aa1122ec25d15a2a73a295f8298ad9c38b09a10/src/rustllvm/RustWrapper.cpp#L387). If anyone has any insight on this, that would be awesome!

Fix out of bounds access by checking length equality BEFORE accessing by index.

Fixes rust-lang#5780

changelog: fix out of bounds access in unnested_or_patterns lint.

Edit: I did not bother reducing a testcase from `librustc_typeck` crate but I can confirm that with the change the crash no longer occurs.
