Implement proper field resolution order.

The lookup methods on appInfo for fields now always traverse both
field chains (static and instance) and find the first match in the
subtyping chain, as is mandated by the JVM spec. If the looked up
field does not match the requested kind, null is returned.

The tree-shaker, on the other hand, will also mark fields of the
wrong kind live if they are reachable, thus ensuring the correct
runtime semantics (thrown Exception, shadowed other field).
