152cbaade7 Move functions from syntax::ast to syntax::ast_util 
This leaves syntax::ast just defining the AST, which strikes me as somewhat
nicer

7d08678b74 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.

Closes #857

1a45a84e73 Start using copy glue to copy bits that may contain ivecs 
This is not currently necessary, but will be, when I land the new ivec
representation.

42864377a4 Remove silly restriction on passing type params by alias 
Since they are now passed by pointer, this is no longer a problem

10269dfaeb Replace &ty::t with ty::t throughout the compiler 
Type handles are uints, passing them by reference only causes
unnecessary spilling.

081caf5bb8 Do not check for self-assign unless dest is initialized 
Also, give copy_val and move_val a more sane return type.

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.

Breaks tail calls.

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.

84fb821e40 Try harder to disambig blocks followed by various exprs in pprust. Closes #840 
As it turns out, it's not just unops we need to worry about. Also tuples and
anything that requires parens.
