4c9c1cd199 Fix dependency bug iface-did-of-impl resolving

7c7559edaf Disallow variable names that shadow tags in scope
Now, if you have a tag named "foo", a variable declaration like
"let foo..." is illegal. This change makes it possible to eliminate
the '.' after a nullary tag pattern in an alt (but I'll be doing
that in a future commit) -- as now it's always obvious whether a
name refers to a tag or a new declared variable.

resolve implements this change -- all the other changes are just to
get rid of existing code that declares variables that shadow tag
names.

94d40be746 Prevent typenames in param bounds from resolving to their own param
I.e. fn foo<T: seq<T>>(...). This leads to weird circularities that seem to
never make any sense, so it seems prudent to forbid it.

a7e1a35f88 Properly typecheck and compile invocations of generic methods.
Aligning the type parameters of the ifaces, impls, and methods
correctly in typeck is almost brain surgery. Seems to work now for
everything I threw at it, but might still break in other corner cases.

057617c665 Parse iface items and interface references in impl items.
The (temporary) syntax is

    iface seq<T> {
        fn len() -> uint;
        fn iter(f: block(T));
    }

    // The 'blah<T>' can be left of to default the name of the
    // impl to seq<T>. The 'of seq<T>' can be left off when
    // not implementing a named interface.
    impl blah<T> of seq<T> for [T] {
        fn len() -> uint { vec::len(self) }
        fn iter(f: block(T)) { for x in self { f(x); } }
    }

619d7c3f72 Associate names with types introduced by items
Issue #828

This is not a full solution yet. To really get sane error messages,
we'll also have to guess the name to apply to literals, which seems
non-trivial.

whole matched value.
