Closes #6183.
The first commit changes the compiler's method of treating a `for` loop, and all the remaining commits are just dealing with the fallout.
The biggest fallout was the `IterBytes` trait, although it's really a whole lot nicer now because all of the `iter_bytes_XX` methods are just and-ed together. Sadly there was a huge amount of stuff that's `cfg(stage0)` gated, but whoever lands the next snapshot is going to have a lot of fun deleting all this code!

Fix for #6306
|
|
&str can be turned into @~str on demand, using to_owned(), so for
strings, we can create a specialized interner that accepts &str for
intern() and find() but stores and returns @~str.

They're still parsed though, to get through bootstrapping.

I just had `git apply` fix most of them and then did a quick skim over the diff to fix a few cases where it did the wrong thing (mostly replacing tabs with 4 spaces, when someone's editor had them at 8 spaces).

mutable fields in the process

The drop block has been deprecated for quite some time. This patch series removes support for parsing it and all the related machinery that made drop work.
As a side feature of all this, I also added the ability to annote fields in structs. This allows comments to be properly associated with an individual field. However, I didn't update `rustdoc` to integrate these comment blocks into the documentation it generates.

This commit does not remove `ty::arg`, although that should be
possible to do now.

the name no longer made sense. perhaps this could just be inlined.

two problems with the old name: they're not called classes any more, and
the word "item" has a specific connotation in the parser
|

before this change, the parser would parse 14.a() as a method call, but
would parse 14.ø() as the floating-point number 14. followed by a function
call. This is because it was checking is_alpha, rather than ident_start,
and was therefore wrong with respect to unicode.
