Use a bitset to represent built-in bounds. There are several places in the language where only builtin bounds (aka kinds) will be accepted, e.g. on closures, destructor type parameters perhaps, and on trait types.

Adds an `uninit` intrinsic.
It's just an empty function, so llvm optimizes it down to nothing.
I changed all of the `init` intrinsic usages to `uninit` where it seemed appropriate to.

Hi there,
Really enjoying Rust. Noticed a few typos so I searched around for a few more--here's some fixes.
Ran `make check` and got `summary of 24 test runs: 4868 passed; 0 failed; 330 ignored`.
Thanks!

At the moment this only includes type checking and there is no code generation support yet. I wanted to get the design reviewed first.
From discussion with @graydon at #5841, re-implemented as `#[simd]` attribute on structs.
Progressing towards #3499.

This pulls all the logic for discovering the crate entry point into a new pass (out of resolve and typeck), then changes it so that main is only looked for at the crate level (`#[main]` can still be used anywhere).
I don't understand the special android logic here and worry that I may have broken it.
This "finishes" the generic deriving code (which I started in #5640), in the sense it supports everything that I can think of being useful. (Including lifetimes and type parameters on methods and traits, arguments and return values of (almost) any type, static methods.)
It closes#6149, but met with #6257, so the following doesn't work:
```rust
#[deriving(TotalEq)]
struct Foo<'self>(&'self int);
```
(It only fails for `TotalOrd`, `TotalEq` and `Clone`, since they are the only ones that call a method directly on sub-elements of the type, which means that the auto-deref interferes with the pointer.)
It also makes `Rand` (chooses a random variant, fills the fields with random values, including recursively for recursive types) and `ToStr` (`x.to_str()` is the same as `fmt!("%?", x)`) derivable, as well as converting IterBytes to the generic code (which made the code 2.5x shorter, more robust and added support for tuple structs).
({En,De}codable are trickier, so I'll convert them over later.)
Also fixed the docstring on `TC_ONCE_CLOSURE` (was accidentally the same as `TC_MUTABLE`) and shifted the `TC_EMPTY_ENUM` bit left by one since whatever previously used that bit has been removed.
Closes#5392 and #5393
I implemented the pop/swap methods for TrieMap/TreeMap/SmallIntMap, and I also updated all of them such that pop isn't just a remove/insert, but rather it's all done in one operation.
One thing I did notice is that with default methods it'd be really nice to define `insert` and `remove` in terms of `pop` and `swap` (or vice versa, just to have them available).
I just had `git apply` fix most of them and then did a quick skim over the diff to fix a few cases where it did the wrong thing (mostly replacing tabs with 4 spaces, when someone's editor had them at 8 spaces).
