Propagate reachability through reexported impls

When re-exporting a trait/structure/enum, then we need to propagate the
reachability of the type through the methods that are defined on it.

Closes #9906
Closes #9968
rustdoc: Don't overflow long type/module names

Closes #9862
fix the new floating point intrinsics
Register snapshots
rustdoc: Render default methods for impls as well

This does not work for cross-crate implementations of traits. Cross-crate
implementations are a separate issue that should be addressed separately.
Basically when an implementation of an external trait is detected, the trait
would have to be loaded at that time (or possibly sooner...). Rustdoc currently
doesn't have the proper infrastructure for adding this.

Closes #9985
cc #9999
std: Move sys::log_str to repr::repr_to_str. Further work on #2240.

syntax: Add the Bug Report HOWTO URL to the ICE message

And also reference the bug report HOWTO in CONTRIBUTING.md
Add support for nested comments

Fixes #9468.
auto merge of #10000 : cmr/rust/snapshot, r=alexcrichton
auto merge of #9936 : madjar/rust/master, r=alexcrichton

This should close #9468.

I removed the test stating that nested comments should not be implemented.

I had a little chicken-and-egg problem because a comment of the std contains "/*", and adding support for nested comment creates a backward incompatibility in that case, so I had to use a dirty hack to get stage1 and stage2 to compile. This part should be revert when this commit lands in a snapshot.

This is my first non-typo contribution, so I'm open to any comment.
