1ba4ca4c4a
allow fn exprs to omit arg types
...
also, avoid using type variables for fn args with omitted types
unless necessary. This will be important for bound regions in
fn types.
fixes #2093

Stop inferring bot/static when types/regions are unconstrained.
...
Also, some other changes that came up along the way:
- add a 'blk' region for the current block.
- detect unused type/region variables.

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.

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)

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/ )
