Changed representation of GETTER/SETTER identifiers. The getter/setter information is now stored directly in struct identifier, rather than embedded in the program code. This means that getter/setters implemented in C won't need to allocate any space for the program code. It also does away with one level of indirection, which should improve performance marginally.
