The functions BitSet::{iter,union,symmetric_difference} each had docs that claimed u32s were output when their actual output each end up being usizes.

They're only enabled in debug builds, but a panic is usually more
welcome than UB in debug builds.

Rustdoc fixes for associated items
This is related to isssue #22442 and solves it partly.
This solves the search index links of associated types and constants,
so that they link to the trait page.
Also add an Associated Constants section if constants are present.
We don't need to copy any elements if `at` is behind the last element
in the map. The last element is at index `self.v.len() - 1`, so we
should not copy if `at` is greater **or equals** `self.v.len()`.

Hiiii, I've got another chunk of updates to the grammar documentation! ⭐🌟🌠
Chipping away at #22445, still have some more to go. I'm learning so much!!!
Maybe it's me, but I really needed an example to understand if let and refutable statements.

Let me know if the variable names are too, uh, culinary.
Several Minor API / Reference Documentation Fixes
- Fix a few small errors in the reference.
- Fix paper cuts in the API docs.
Fixes#24882Fixes#25233Fixes#25250
The reference was claiming all vectors all bounds-checked at run-time, when constant vectors are usually checked at compile-time.
For the changed example see http://is.gd/28ak9E
Also fixed a minor grammar issue.
We don't need to copy any elements if `at` is behind the last element
in the map. The last element is at index `self.v.len() - 1`, so we
should not copy if `at` is greater or equals `self.v.len()`.
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 :)
Between ffc5f1c, when grammar.md was created by copying parts of the
reference, and 8cf2552, when all EBNF was removed from reference.md,
there were parts of the grammar that were updated in reference.md but
not grammar.md, and then they weren't copied over because they existed
already, but they were slightly out of date.
Example: the `path_item : ident | "self" ;` rule in Use declarations was
changed from "mod" to "self" in the reference in 195fd9a but wasn't
updated in the grammar.
