This commit is an implementation of [RFC 1040][rfc] which is a redesign of the
currently-unstable `Duration` type. The API of the type has been scaled back to
be more conservative and it also no longer supports negative durations.
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1040-duration-reform.md
The inner `duration` module of the `time` module has now been hidden (as
`Duration` is reexported) and the feature name for this type has changed from
`std_misc` to `duration`. All APIs accepting durations have also been audited to
take a more flavorful feature name instead of `std_misc`.
Closes #24874

Reading through the rendered error explanations in http://doc.rust-lang.org/error-index.html, I noticed a few opportunities to improve the output.

There is no subtyping relationship between the types (or their non-freshened
variants), so they can not be merged.
Fixes #22645
Fixes #24352
Fixes #23825
Should fix #25235 (no test in issue).
Should fix #19976 (test is outdated).

* segfault due to not copying drop flag when coercing
* fat pointer casts
* segfault due to not checking drop flag properly
* debuginfo for DST smart pointers
* unreachable code in drop glue

+ lots of rebasing

At the moment, http://doc.rust-lang.org/error-index.html isn't linked to from anywhere (except Reddit). This should allow search engines to find error codes!
I also capitalised "The Standard Library" and neatened a few bits of grammar.
Also fixed: `#[main]` inside one of the error descriptions.

The loop to load all the known impls from external crates seems to have been used because `ty::populate_implementations_for_trait_if_necessary` wasn't doing its job, and solely relying on it resulted in loading only impls in the same crate as the trait.
Coherence for `librustc` was reduced from 18.310s to 0.610s, from stage1 to stage2.
Interestingly, type checking also went from 46.232s to 42.003s, though that could be noise or unrelated improvements.
On a smaller scale, `fn main() {}` now spends 0.003s in coherence instead of 0.368s, which fixes #22068.
It also peaks at only 1.2MB, instead of 16MB of heap usage.

impls from all the crates.

clear that it only populates inherent impls.

There were still some mentions of `~[T]` and `~T`, mostly in comments and debugging statements. I tried to do my best to preserve meaning, but I might have gotten some wrong-- I'm happy to fix anything :)

This was added in d2f8074 along with the AssocSpace stuff. The AssocSpace
stuff was then removed in de8e0ae, except it seems the comment here was missed.

Part of #24407.
|
|
|
|
An automated script was run against the `.rs` and `.md` files,
subsituting every occurrence of `task` with `thread`. In the `.rs`
files, only the texts in the comment blocks were affected.

Fix #25076.

The error message was misleading, so I adjusted it, and I also added the long diagnostics for this error (resolves one point in #24407).
I was unsure about how to phrase the error message. Is “generic parameter binding” the correct term for this?

Depends on #24921. r? @alexcrichton

Turns out that a verbatim path was leaking through to gcc via the PATH
environment variable (pointing to the bundled gcc provided by the main
distribution) which was wreaking havoc when gcc itself was run. The fix here is
to just stop passing verbatim paths down by adding more liberal uses of
`fix_windows_verbatim_for_gcc`.
Closes #25072

Leftovers from @-pointer times, I guess.
|
|
This uses a (per-trait) hash-table to separate impls from different TraitDefs, and makes coherence go so much quicker. I will post performance numbers tomorrow.
This is still WIP, as when there's an overlap error, impls can get printed in the wrong order, which causes a few issues. Should I pick the local impl with the smallest NodeId to print?
Could you take a look at this @nikomatsakis?
