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".

15b540ded4 Use a single builder object throughout
This seems to be faster than creating separate ones for each block
context.

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.

Reduces compiler code size by 3%
