Most Iterators renamed to make their naming more consistent. Most significantly, the Iterator and Iter suffixes have been completely removed.

1e20960f79 Actually force a / in the path for ext crates
If the library is in the working directory, its path won't have a "/"
which will cause dlopen to search /usr/lib etc. It turns out that Path
auto-normalizes during joins so Path::new(".").join(path) is actually a
no-op.

ae2a5ecbf6 handle zero-size allocations correctly
The `malloc` family of functions may return a null pointer for a
zero-size allocation, which should not be interpreted as an
out-of-memory error.

If the implementation does not return a null pointer, then handling
this will result in memory savings for zero-size types.

This also switches some code to `malloc_raw` in order to maintain a
centralized point for handling out-of-memory in `rt::global_heap`.

f4498c71e2 auto merge of #11497 : huonw/rust/trie-internal-iter, r=alexcrichton
This stores the stack of iterators inline (we have a maximum depth with
`uint` keys), and then uses direct pointer offsetting to manipulate it,
in a blazing fast way:

Before:

    bench_iter_large          ... bench:     43187 ns/iter (+/- 3082)
    bench_iter_small          ... bench:       618 ns/iter (+/- 288)

After:

    bench_iter_large          ... bench:     13497 ns/iter (+/- 1575)
    bench_iter_small          ... bench:       220 ns/iter (+/- 91)

Also, removes `.each_{key,value}_reverse` as an offering to
placate the gods of external iterators for my heinous sin of 
attempting to add new internal ones (in a previous version of this
PR).

472dfe74b3 Simplify std::num::Primitive trait definition
This removes the `Primitive::{bits, bytes, is_signed}` methods and removes the operator trait constraints, for the reasons outlined below:

- The `Primitive::{bits, bytes}` associated functions were originally added to reflect the existing `BITS` and `BYTES` statics included in the numeric modules. These statics are only exist as a workaround for Rust's lack of CTFE, and should probably be deprecated in the future in favor of using the `std::mem::size_of` function (see #11621).

- `Primitive::is_signed` seems to be of little utility and does not seem to be used anywhere in the Rust compiler or libraries. It is also rather ugly to call due to the `Option<Self>` workaround for #8888.

- The operator trait constraints are already covered by the `Num` trait.

4098327b1f auto merge of #11585 : nikomatsakis/rust/issue-3511-rvalue-lifetimes, r=pcwalton
Major changes:

- Define temporary scopes in a syntax-based way that basically defaults
  to the innermost statement or conditional block, except for in
  a `let` initializer, where we default to the innermost block. Rules
  are documented in the code, but not in the manual (yet).
  See new test run-pass/cleanup-value-scopes.rs for examples.
- Refactors Datum to better define cleanup roles.
- Refactor cleanup scopes to not be tied to basic blocks, permitting
  us to have a very large number of scopes (one per AST node).
- Introduce nascent documentation in trans/doc.rs covering datums and
  cleanup in a more comprehensive way.

4be3262058 syntax::ext: replace span_fatal with span_err in many places.
This means that compilation continues for longer, and so we can see more
errors per compile. This is mildly more user-friendly because it stops
users having to run rustc n times to see n macro errors: just run it
once to see all of them.

ed7e576d9c Add a generic power function
The patch adds a `pow` function for types implementing `One`, `Mul` and
`Clone` trait.

The patch also renames f32 and f64 pow into powf in order to still have
a way to easily have float powers. It uses llvms intrinsics.

The pow implementation for all num types uses the exponentiation by
square.

8f16356e5f Extend temporary lifetimes if there is a ref in an enum binding
too.

Previously I had omitted this case since function calls don't get the same
treatment on the RHS, but it's different on the pattern and is more consistent
-- the goal is to identify `let` statements where `ref` bindings create
interior pointers.

Use a lookup table, SHIFT_MASK_TABLE, that for every possible four
bit prefix holds the number of times the value should be right shifted and what
the right shifted value should be masked with. This way we can get rid of the
branches which in my testing gives approximately a 2x speedup.
