This allows the internal implementation details of the TLS keys to be
changed without requiring the update of all the users. (Or, applying
changes that *have* to be applied for the keys to work correctly, e.g.
forcing LLVM to not merge these constants.)

Replace the remaining functions marked for issue #8228 with similar functions that are iterator-based.
Change `either::{lefts, rights}` to be iterator-filtering instead of returning a vector.
Replace `map_vec`, `map_vec2`, `iter_vec2` in std::result with three functions:
* `result::collect` gathers `Iterator<Result<V, U>>` to `Result<~[V], U>`
* `result::fold` folds `Iterator<Result<T, E>>` to `Result<V, E>`
* `result::fold_` folds `Iterator<Result<T, E>>` to `Result<(), E>`
This allows the internal implementation details of the TLS keys to be
changed without requiring the update of all the users. (Or, applying
changes that have to be applied for the keys to work correctly, e.g.

The span was fixed at some point to point to the correct character, but
the error message is still bad. Update it to emit the actual character
in question (potentially escaped).
Fixes#3747.
When parsing a trait function, the function must end with either `;` or
`{` (signifying a default implementation). The error message incorrectly
stated that it must be `;` or `}`.
Fixes#6610.
Pointers to bound variables shouldn't be stored before checking pattern,
otherwise piped patterns can conflict with each other (issue #6338).
Closes#6338.
Fixes#7722
I had a couple of queries:
- Should this return an array or an iterator?
- Should this be a method on iterators or on the rng? I implemented it in RngUtils as it seemed to belong with shuffle().
