Closes #8118, #7136

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)

1aae28a57d Replaces the free-standing functions in f32, &c.
The free-standing functions in f32, f64, i8, i16, i32, i64, u8, u16,
u32, u64, float, int, and uint are replaced with generic functions in
num instead.

If you were previously using any of those functions, just replace them
with the corresponding function with the same name in num.

Note: If you were using a function that corresponds to an operator, use
the operator instead.

a1531ed946 librustc: Remove the broken overloaded assign-ops from the language.
They evaluated the receiver twice. They should be added back with
`AddAssign`, `SubAssign`, etc., traits.

7aee5da08d auto merge of #7254 : Blei/rust/intrinsic-overhaul, r=cmr
This sets the `get_tydesc()` return type correctly and removes the intrinsic module. See #3730, #3475.

Update: this now also removes the unused shape fields in tydescs.

e2f1049bd5 Remove unused TyDesc parameter from the glue functions
To remove the environment pointer, support for function pointers without
an environment argument is needed (i.e. a fixed version of #6661).

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.

8114d0e950 librustc: Disallow multiple patterns from appearing in a "let" declaration.
You can still initialize multiple variables at once with "let (x, y) = (1, 2)".

0c820d4123 libstd: Rename libcore to libstd and libstd to libextra; update makefiles.
This only changes the directory names; it does not change the "real"
metadata names.
