Support non-canonical static type imports

The JLS permits static type imports to refer to types using
non-canonical names, e.g. `java.util.Map.Entry` can be resolved from
either of these imports:

import static java.util.HashMap.Entry;
import static java.util.HashMap.*;

Historically this feature has not been well-supported by javac
[1][2][3][4], it is bad style [5][6], and a vanishingly small amount of
real world code uses it.  Nevertherless, it's in the spec.
