These are all in the prelude so most code will not break.

This makes edge cases in which the `Iterator` trait was not in scope
and/or `Option` or its variants were not in scope work properly.
This breaks code that looks like:
struct MyStruct { ... }
impl MyStruct {
fn next(&mut self) -> Option<int> { ... }
}
for x in MyStruct { ... } { ... }
Change ad-hoc `next` methods like the above to implementations of the
`Iterator` trait. For example:
impl Iterator<int> for MyStruct {
fn next(&mut self) -> Option<int> { ... }
}
Closes#15392.

This is a migration of the std::{f32, f64}::to_str* functionality to the core
library. This removes the growable `Vec` used in favor of a large stack buffer.
The maximum base 10 exponent for f64 is 308, so a stack buffer of 512 bytes
should be sufficient to store all floats.
