Changes the ad-hoc closure adjustment into using adjustment info instead
of being separately driven from types, and likewise for autoderef.

Also takes care of autoref (the cases we should be seeing in consts,
at least, since we can't be doing method calls which would need the
ref-to-vec mode), which didn't quite work right previously.

However, "dereference" of a newtype isn't handled yet....

parser bugs that this uncovered.

Two small changes: `Not` was missing from the list of core traits and `assert` was removed from the language.

This makes `#[deriving_clone]` useful.

I wasn't sure if a macro was the right way to do this, but it seems more maintainable than a series of repetitive `impl`s.

`log` can  polymorphically log anything, but debug!, etc. requires a format string. With this patch you can equivalently write `debug!(foo)` or `debug!("%?", foo)`.

I'm doing this because I was trying to remove `log` (replacing it with nothing, at least temporarily), but there are a number of logging statements that just want to print an arbitrary value and don't care about the format string.

I'm not entirely convinced this is a good change, since it overloads the implementation of these macros and makes their usage slightly more nuanced.

I missed this when I replaced iter-trait with a `BaseIter` impl.

Closes #4985 by removing the `dvec` module and all use cases throughout the compiler.

A number of uses were directly convertible to `let mut foo = ~[];`, while others in hash maps and some fields had to be converted to `@mut ~[T]`. A small number of `DVec` instances in fields were able to be converted directly to `~[T]` without the `@`, but this was a difficult thing to do.
