54cf0e9c0d Use precise return type to allocate retslot in trans_args 
Using type_of_or_i8 did, predictably, allocate an i8 for a type parameter,
which leads to memory corruption and general confusion.

Closes #1443

Also, move checking of ifaces into the collect phase of typeck
to give further passes some guarantees.

3eb35900c7 Remove ty::bind_params_in_type

3971b520bc Use the right types for methods in trans_impl 
This prevents misalignment between function and argument
types in corner cases.

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.

    }

    // 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); } }
