e1a26ad271 use element count in slices, not size in bytes 
This allows the indexing bounds check or other comparisons against an
element length to avoid a multiplication by the size.

4cc925a5f4 Register new snapshots 
Now that #9662 is merged, we should be much more easily bootstrappable on
windows now.

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

d09f569aac auto merge of #9065 : thestinger/rust/iter, r=alexcrichton 
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.

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.

180e235d3d fix performance regression from invalid IR 
Monomorphize's normalization results in a 2% decrease in non-optimized
code size for libstd, so there's a negligible cost to removing it. This
also fixes several visit glue bugs because normalize wasn't considering
the differences in visit glue between types.

5aaaca0c6a Consolidate raw representations of rust values 
This moves the raw struct layout of closures, vectors, boxes, and strings into a
new `unstable::raw` module. This is meant to be a centralized location to find
information for the layout of these values.

As safe method, `repr`, is provided to convert a rust value to its raw
representation. Unsafe methods to convert back are not provided because they are
rarely used and too numerous to write an implementation for each (not much of a
common pattern).

469f394b25 Remove intrinsic module 
To achieve this, the following changes were made:
* Move TyDesc, TyVisitor and Opaque to std::unstable::intrinsics
* Convert TyDesc, TyVisitor and Opaque to lang items instead of specially
  handling the intrinsics module
* Removed TypeDesc, FreeGlue and get_type_desc() from sys

Fixes #3475.
