Fix for erroneous bytecode generation.

A remedy for an IllegalAccessError where generated bytecode referred to
an inaccessible type. Closes SI-1430.

Bonus materials:

 - tore out all the invokedynamic support.  The shipped jdk7
 implementation shows limited resemblance to the one this was written
 against; the code mostly serves to distract.  (I think I could get
 invokedynamic working pretty quickly, except that it would
 mean having a codebase for java7 and one for 5-6, which is not a yak
 I wish to shave today.)

 - gave NullClass and NothingClass objects of their own, which
 allowed a nice polymorphic simplification of isSubClass, plus a
 couple other streamlinings.
