This patch finishes removing inner vector mutability from the vast majority of the compiler. Exceptions:
* core::dvec: ideally this entire type will be able to be replaced by `~[]`, but Niko asked me to hold off on removing Dvecs until he makes some fixes to borrowed pointers.
* liveness: liveness.rs is an impenetrable neutron star of deprecated semantics.
* compile-fail: I'm not sure if a lot of these tests are testing inner mutability or mutability in general. I figure that RIMOVing this folder should wait until this syntax is removed from the parser.
I also took this chance to remove many of the inner-mutability-related functions from core::vec, or as many uses of those functions as possible where still necessary. consume_mut and append_mut have been axed. cast_to_mut and cast_from_mut are still needed in a few places.

values to be copied. Rewrite kind computation so that instead of directly
computing the kind it computes what kinds of values are present in the type,
and then derive kinds based on that. I find this easier to think about.
Fixes#4821.

5283a8b reworks the TreeMap lazy iterator to use `&mut` again, which closes#4763. It gets the performance of the set methods back in the same ballpark that it was pre-INHTWAMA which is nice. These can be turned back into methods eventually.
e5b6334 removes the transitional smallintmap attributes which closes#4737.
Also adds Rng::gen() for generically generating any type that implements the Rand trait. There's no way to generate things with a length (for e.g. strings or vectors), because I can't think of an elegant way to do that. Maybe have a RandLen trait that inherits Rand?
This can be used for a quickcheck mechanism I'm working on.
