std: IPv6 addresses are represented as eight groups of four HEXADECIMAL digits
Represent C-like enums with a plain LLVM integer, not a struct.

This is needed so that the FFI works as expected on platforms that don't
flatten aggregates the way the AMD64 ABI does, especially for `#[repr(C)]`.

This moves more of `type_of` into `trans::adt`, because the type might
or might not be an LLVM struct.

Take &Pat

Take &Pat in visit_pat
Add an implementation of Encodable and Decodable for Rc. This will be needed to use Rc in place of @ in libsyntax.
Implement IterBytes for Rc<T>.
auto merge of #10657 : sanxiyn/rust/pat, r=cmr
auto merge of #10658 : LeoTestard/rust/serialize-rc, r=cmr

Implement various traits (IterBytes and extra's Encodable and Decodable) for Rc<T> when T alreay implements the trait.
auto merge of #10650 : andreasots/rust/ipv6-is-in-hex, r=alexcrichton

Without this the assert in <tt>rust_malloc_ip6_addr</tt> is triggered as it expects a correctly formatted IPv6 address.
Move LittleLock to using RAII

This moves the locking/waiting methods to returning an RAII struct instead of
relying on closures. Additionally, this changes the methods to all take
'&mut self' to discourage recursive locking. The new method to block is to call
`wait` on the returned RAII structure instead of calling it on the lock itself
(this enforces that the lock is held).

At the same time, this improves the Mutex interface a bit by allowing
destruction of non-initialized members and by allowing construction of an empty
mutex (nothing initialized inside).
Fix the usual check-fast scoping mistake.
