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!
I changed ```RED_ZONE_SIZE``` to ```RZ_MAC_32``` because of stack canary failure.
Here is a LLVM patch for MIPS segmented stacks.

&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.
This improves error reporting for the following class of imports:
```rust
use foo::bar;
```
Where foo, the topmost module, is unresolved. It now results in:
```text
/tmp/foo.rs:1:4: 1:7 error: unresolved import. perhapsyou forgot an 'extern mod foo'?
/tmp/foo.rs:1 use foo::bar;
^~~
/tmp/foo.rs:1:4: 1:12 error: failed to resolve import: foo::bar
/tmp/foo.rs:1 use foo::bar;
^~~~~~~~
error: failed to resolve imports
error: aborting due to 3 previous errors
```
This is the first of a series of changes I plan on making to unresolved name error messages.
As noted by @jwise [here](52445129fd (commitcomment-3172192)), it's probably a good idea to keep these unsafe.
The lint check won't warn about these because it ignore `unsafe fn` declarations.
Use a bitset to represent built-in bounds. There are several places in the language where only builtin bounds (aka kinds) will be accepted, e.g. on closures, destructor type parameters perhaps, and on trait types.

Fix#6355 and #6272---we were not giving the correct index to the derefs that occur as part of the rooting process, resulting in extra copies and generally bogus behavior. Haven't quite produced the right test for this, but I thought I'd push the fix in the meantime. Test will follow shortly.

Adds an `uninit` intrinsic.
It's just an empty function, so llvm optimizes it down to nothing.
I changed all of the `init` intrinsic usages to `uninit` where it seemed appropriate to.
I removed some of the copies, but most are just made explicit. The usage in `libcore` was already fixed, but the attribute was only set to warn (not removed).

Hi there,
Really enjoying Rust. Noticed a few typos so I searched around for a few more--here's some fixes.
Ran `make check` and got `summary of 24 test runs: 4868 passed; 0 failed; 330 ignored`.
Thanks!
Sean
