implement raw pointer comparisons in librustc
...
This is mostly for consistency, as you can now compare raw pointers in
constant expressions or without the standard library.
It also reduces the number of `ptrtoint` instructions in the IR, making
tracking down culprits of what's usually an anti-pattern easier.

rename std::iterator to std::iter
...
The trait will keep the `Iterator` naming, but a more concise module
name makes using the free functions less verbose. The module will define
iterables in addition to iterators, as it deals with iteration in
general.

auto merge of #8596 : vadimcn/rust/master, r=alexcrichton
...
This resolves issue #908 .
Notable changes:
- On Windows, LLVM integrated assembler emits bad stack unwind tables when segmented stacks are enabled. However, unwind info directives in the assembly output are correct, so we generate assembly first and then run it through an external assembler, just like it is already done for Android builds.
- Linker is invoked via "g++" command instead of "gcc": g++ passes the appropriate magic parameters to the linker, which ensure correct registration of stack unwind tables in dynamic libraries.

vec: use offset_inbounds for iterators

This allows LLVM to optimize vector iterators to an `getelementptr` and
`icmp` pair, instead of `getelementptr` and *two* comparisons.

std and rustc: explicitly pass c strings to c functions

When strings lose their trailing null, this pattern will become dangerous:

update ptr intrinsics and rewrite vec routines to be more correct.

In particular, it is not valid to go around passing uninitialized or zero'd
memory as arguments. Rust should generally be free to assume that the arguments
it gets are valid input values, but the output of intrinsics::uninit() and
intrinsics::init() are not (e.g., an @T is just null, leading to an error
if we should try to increment the ref count).
