1c56652640 auto merge of #10064 : luqmana/rust/vvv, r=nikomatsakis 
Fixes #2057.

Example:
```Rust
#[no_std];

type c_char = u8;
type c_int = i32;
type size_t = uint;

extern {
    fn printf(format: *c_char, ...) -> c_int;
}

#[lang="fail_bounds_check"]
fn fail_bounds_check(_: *c_char, _: size_t, _: size_t, _: size_t) {}

#[start]
#[fixed_stack_segment]
fn main(_: int, _: **u8) -> int {
    unsafe {
        let msg = bytes!("Hello World!

4b04395c11 auto merge of #10182 : alexcrichton/rust/typeid-intrinsic, r=nikomatsakis 
This isn't quite as fancy as the struct in #9913, but I'm not sure we should be exposing crate names/hashes of the types. That being said, it'd be pretty easy to extend this (the deterministic hashing regardless of what crate you're in was the hard part).

fcfbfde0b7 Adjust reflection for the possibility of discriminants larger than int. 
Not only can discriminants be smaller than int now, but they can be
larger than int on 32-bit targets.  This has obvious implications for the
reflection interface.  Without this change, things fail with LLVM
assertions when we try to "extend" i64 to i32.

88ab38cf06 Removed the -Z once_fns compiler flag and added the new feature directive of the same name to replace it. 
Changed the frame_address intrinsic to no longer be a once fn.
This removes the dependency on once_fns from std.

16fc6a694c Remove unused abi attributes. 
They've been replaced by putting the name on the extern block.

  #[abi = "foo"]

goes to

  extern "foo" { }

Closes #9483.

c9d4ad07c4 remove the float type 
It is simply defined as `f64` across every platform right now.

A use case hasn't been presented for a `float` type defined as the
highest precision floating point type implemented in hardware on the
platform. Performance-wise, using the smallest precision correct for the
use case greatly saves on cache space and allows for fitting more
numbers into SSE/AVX registers.

If there was a use case, this could be implemented as simply a type
alias or a struct thanks to `#[cfg(...)]`.

Closes #6592

At the same time, this updates the TyVisitor to use a mutable self because it's
probably going to be mutating state as it goes along anyway.

3e933b199c auto merge of #7194 : jensnockert/rust/endian, r=cmr 
They simply byte-swap an integer to a specific endian, like the hton* functions in C.

These intrinsics are synthesized, so maybe they should be in another file. But since they are just a single line of code each, based on the bswap intrinsics and aren't really intended for public consumption I thought they would fit in the intrinsics file.

The next step working on this could be to expose a trait / generic function for byteswapping.
