We force the usage of LF line endings, but *only* in text files.

util: remove unused `with` function
Uncomment a test. Fixes #4449.
Fix spelling and phrasing in 0.8 release notes
Add a note about improved rustc perf to 0.8 relnotes
Fix example in std::Option
std: add missing #[inline] annotation to the f64 neg method.

This was, somehow, missed by #8332.

auto merge of #9350 : pnkfelix/rust/fsk-issue-4691-catch-bad-fsu-during-compute-moves, r=nikomatsakis

Resolves third bullet of #4691: if the functional-struct-update (FSU) expression `{ a: b, ..s }` causes `s` to move and `s` has a destructor, then the expression is illegal.

drop `extra::par`

This was a dead end experiment, and not a sensible way of implementing
generic data parallelism. This also removes the `graph500-bfs.rs`
benchmark because it relies on `extra::par`.

Closes #9379
Implement a web backend for rustdoc_ng

This large commit implements and `html` output option for rustdoc_ng. The
executable has been altered to be invoked as "rustdoc_ng html <crate>" and
it will dump everything into the local "doc" directory. JSON can still be
generated by changing 'html' to 'json'.

This also fixes a number of bugs in rustdoc_ng relating to comment stripping,
along with some other various issues that I found along the way.

The `make doc` command has been altered to generate the new documentation into
the `doc/ng/$(CRATE)` directories.

Missing features
* Different versions of documentation on the same page (all possibly indexed as well?) I think that this needs to be thought out before action is taken. It's an awesome idea, but it should be done carefully.
* Source links are missing. This is a little dependent on getting versions working. In theory we should link back to github, but we should always link back to the exact version the documentation was generated from.
* Integration with other tools. It would be awesome to have rustpkg-style inference of the package name and version so they don't have to be specified anywhere. Additionally, I should be able to build documentation for a pkgid, not necessarily a crate file.
