Before:
test bench_from_elem ... bench: 415 ns/iter (+/- 17)
test bench_set_memory ... bench: 85 ns/iter (+/- 4)
test bench_vec_repeat ... bench: 83 ns/iter (+/- 3)
After:
test bench_from_elem ... bench: 84 ns/iter (+/- 2)
test bench_set_memory ... bench: 84 ns/iter (+/- 5)
test bench_vec_repeat ... bench: 84 ns/iter (+/- 3)

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).

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.

Adds documentation for various things that I understand.
Adds #[allow(missing_doc)] for lots of things that I don't understand.

This only changes the directory names; it does not change the "real"
metadata names.
