ARC is beginning to infect more and more types, and they each must have a clone method, but there is no trait to implement.

Along with this, we should provide a default implementation of Clonable for all copyable types.

Closing this now that #[deriving_clone] has been implemented. There are no doubt some types left that should have a Clone implementation, but they can be dealt with on a case-by-case basis.

Improve performance and language support of memory initialization che…
068f63c 
…cks (rust-lang#3313)

This is a follow-up PR for rust-lang#3264, a part of the larger work towards
rust-lang#3300.

This PR introduces:

- Use of demonic non-determinism (prophecy variables) to improve memory
initialization checks performance;
- Instead of keeping track of memory initialization of each possibly
uninitialized byte pointed to by some pointer, one is chosen
non-deterministically;
- Tests for proper memory initialization checks injection for compiler
intrinsics;
- Separate functions for checking memory initialization of slice chunks.
