… semantics. Also added unit tests of range code to test refactoring. The num-range-rev.rs test will need to be updated when the range_rev semantics change.
… only, not type signatures)
…fclosedness-issue5270-2ndpr, r=cmr Changes int/uint range_rev to iterate over range `(hi,lo]` instead of `[hi,lo)`. Fix rust-lang#5270. Also: * Adds unit tests for int/uint range functions * Updates the uses of `range_rev` to account for the new semantics. (Note that pretty much all of the updates there were strict improvements to the code in question; yay!) * Exposes new function, `range_step_inclusive`, which does the range `[hi,lo]`, (at least when `hi-lo` is a multiple of the `step` parameter). * Special-cases when `|step| == 1` removing unnecessary bounds-check. (I did not check whether LLVM was already performing this optimization; I figure it would be a net win to not leave that analysis to the compiler. If reviewer objects, I can easily remove that from the refactored code.) (This pull request is a rebased version of PR rust-lang#7524, which went stale due to recent unrelated changes to num libraries.)
Allowing them in type signatures is a significant amount of extra work, unfortunately. This also doesn't apply to static values, which takes a different code path.

Whenever a lang_item is required, some relevant message is displayed, often with
a span of what triggered the usage of the lang item.
Now "hello word" is as small as:
```rust
#[no_std];
extern {
fn puts(s: *u8);
}
extern "rust-intrinsic" {
fn transmute<T, U>(t: T) -> U;
}
#[start]
fn main(_: int, _: **u8, _: *u8) -> int {
unsafe {
let (ptr, _): (*u8, uint) = transmute("Hello!");
puts(ptr);
}
return 0;
}
```
…lton Add some codegen tests. Nothing too surprising.
