f841e89443 Support unchecked blocks
This patch supports the syntax

    unchecked {
      ...
    }

    to disable purity checking within a block. Presumably it will only be
    used within a declared "pure fn". However, there is no checking that it
    doesn't occur elsewhere, and it would be harmless for it to do so.

    I went with Lindsey's suggestion for the syntax, but it's subject to
    change.

    This allows you to write code that uses predicates that call arbitrary
    Rust functions, but you must declare your intentions by wrapping it in
    an unchecked { ... } block. The test case run-pass/unchecked-predicates.rs
    demonstrates how to do that.

c6155d1fd1 Change "pred" to "pure fn" (but still accept "pred")
This is part 1 of changing the "pred" keyword to "pure fn".
Right now, the compiler accepts both "pred" and "pure fn".

b9112525ba Move to a more lightweight builder system
You now do

    bld::Ret(bcx, someval)

where you used to say

    bcx.build.Ret(someval)

Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.

e58c48bdda Optimize += [x] into a simple push operation
This is a preparation for making vectors always-on-the-heap again,
which would cause way too much malloc traffic for this idiom. I will
add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

When a guard fails, pattern-matching continues with the next pattern.

b24f978011 Drop arguments on the caller side, not the callee
This makes it easier for the caller to optimize the take/drop away for
temporary values, and opens up new possibilities for alias handling.

35c962e9a1 Pass structural types by pointer, not by value
If we lose tail calls, this is possible. It simplifies things a lot.

Direct motivation: We want ivecs with pointers pointing into
themselves. When copying those, the pointers have to be adjusted. It
is impossible to this when copying them with Load/Store.
