Remove binary field
Added link to fourcc docs
Move fourcc to HOST_CRATES

It depends on libsyntax, which is a host crate, so it can't be in the target
crates section.
Reserve `do` as a keyword

Resolves issue #12157. `do` is hereby reinstated as a keyword; no syntax is
associated with it though. Along the way, a unit test had to be adapted, since
it was using `do` as a method identifier.

Breaking changes:

- Any code using `do` as an identifier will no longer work.

The field is unused.
Ignore #[phase] on use view items

Closes #11806

crates section.
Don't use -Z prefer-dynamic at stage0

This is blocking a snapshot because the stage0 target compiler comes from a
stage1 host compiler. This means that the stage0 compiler doesn't actually
understand the -Z prefer-dynamic flag and is dying as a result.

This will get added back to stage0 after a snapshot.
auto merge of #12170 : aepsil0n/rust/feature/reserve_do_keyword, r=brson

This resolves issue #12157. Does that do it already or is there something else that needs taking care of?  

As a side note, there seems to be some documentation, in which the old existence of the do keyword is explained. The list of keywords is not up-to-date either. But these are certainly separate issues.
Factoring bigint, rational, and complex out of libextra into libnum.

Removed use of globs present in earlier versions of modules.

Fix tutorial.md to reflect `extra::rational` ==> `num::rational`.
auto merge of #12175 : sfackler/rust/phase-use-ignored, r=alexcrichton

It could throw an error but I think it's best to not since `#[phase(..)]` syntax in other places would be silently ignored.
