Tests for annotations on inner class aliases and on class alias parameters. ceylon/ceylon-compiler#1298
Reflection: Add method for finding a class alias insantiator methods. ceylon/ceylon-compiler#1298
Support getting annotations from class alias parameters. ceylon/ceylon-compiler#1298
Metamodel: Switch the order of these ifs, because for inner class aliases we were taking the wrong branch. ceylon/ceylon-compiler#1298
