Message:

[codegen] Fix two major bugs: first, make sure we name system classes
correctly when constructing jvm-level type descriptors. Second,
distinguish between dotted method calls on trait-typed receivers
(which require INVOKEINTERFACE) from those on object-typed receivers
(which require INVOKEVIRTUAL). This latter requires some tricky
special-case code for builtin types.

Tried to clean up NamingCzar? and CodeGen? a bit along the way, as
messiness in these classes slowed down bug hunting considerably.
