8e15640ada Refactor operator precedence code 
Use functions instead of a dynamically created table to determine
operator precedence. Gets rid of a FIXME in syntax::parse::prec.
Change precedences from int to uint while we're at it, since
don't use negative precedences.

825fd1808e lots of work to make iface/impls parameterized by regions 
- paths can now take region parameters, replacing the dirty hack
  I was doing before of abusing vstores.  vstores are now a bit
  of a hack though.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)

f7641286b2 Allow classes to be cast to ifaces that are in the same crate 
I had to xfail one existing test case (class-implements-int) because,
I think, of the same bug described in #2272.

37b0549730 Add new syntax for patterns that match the head constructor only 
Adds a new kind of pattern C(*) where C is a constructor that may
have any number of fields. This pattern matches any value
constructed with C, without binding names for any of the fields.

Closes #1701.

31ff64c62d Annotate FIXMEs in parser 
Also, get rid of two FIXMEs by refactoring some code, and moving the
call_expr check for be expressions into typeck, where it seems to
make more sense.

5c12cd72f4 Allow classes to implement ifaces 
Introduce syntax like:

iface animal { ... }
class cat implements animal { ... }

to allow classes to implement ifaces. Casting classes to ifaces
is *not* yet supported. ifaces that a class implements are not
yet included in metadata.

The syntax is subject to change, and may go away completely if we
decide to use duck typing to relate classes with ifaces (see
http://smallcultfollowing.com/babysteps/blog/2012/04/10/declared-vs-duckish-typing/ )

c902eafa14 Convert old-style for loops to new-style 
Most could use the each method, but because of the hack used to
disambiguate old- and new-style loops, some had to use vec::each.

that have their own type parameters.
