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.

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".

Implement pattern guards
...
The syntax is
alt x {
mypat where mycond { ... }
}
The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

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.
Breaks tail calls.
