Initial support for emitting DWARF for static vars.

Only supports crate level statics. No debug info is generated for
function level statics. Closes #9227.
collections: remove List

It was decided in a meeting that this module wasn't needed,
and more thought should be put into a persistent collections
library.
test: remove pure test, which is now redundant with inline tests
std and green: fix some warnings

Only supports crate level statics. No debug info is generated for function level statics. Closes #9227.

As discussed at the end of the comments for #9227, I took an initial stab at adding support for function level statics and decided it would be enough work to warrant being split into a separate issue.

See #13144 for the new issue describing the need to add support for function level static variables.
auto merge of #13183 : erickt/rust/remove-list, r=alexcrichton

`collections::list::List` was decided in a [team meeting](https://github.com/mozilla/rust/wiki/Meeting-weekly-2014-03-25) that it was unnecessary, so this PR removes it. Additionally, it removes an old and redundant purity test and fixes some warnings.
configure: Add MINGW64 OS type

MSYS2 supports `MINGW64` system for 64-bit environment. It sets
`MSYSTEM=MINGW64` environment variable, which changes output of
`uname -s` thus affects `configure` behavior.

This patch adds `MINGW64*` support for `configure`.

Use new inner attribute syntax in test framework
auto merge of #13200 : sfackler/rust/test-attr, r=cmr
Removed deprecated functions `map` and `flat_map` for vectors and slices.
auto merge of #13203 : Kimundi/rust/de-map-vec3, r=cmr

They required unnecessary temporaries, are replaced with iterators, and would conflict with a possible future `Iterable` trait.
Updated references to extra in libcollections docs
make shootout-k-nucleotide.rs pass official test

Correct printing (sort, new lines), reading on stdin, s/i32/uint/,
ignore-android because it reads stdin
auto merge of #13208 : Tohie/rust/master, r=alexcrichton
Check that the old value was 1 and not 0 when dropping a Arc value.
Closed #13210.
Support new attribute syntax in vim syntax file
configure: Accept LLVM 3.4.X during configuration

The previous regex was a bit to strict, rejecting versions such as 3.4.1 which
is apparently the version which travis is currently installing, causing all
travis builds to fail.
auto merge of #13215 : sfackler/rust/vim-attr, r=alexcrichton
auto merge of #13211 : csherratt/rust/arc_fix, r=alexcrichton

This is a fix for #13210. fetch_sub returns the old value of the atomic variable, not the new one.
