Part 3 - merge op_put_getter & op_put_setter.

Putting these separately is inefficient (and makes future optimiation,
e.g. making GetterSetter immutable) harder. Change to emit a single
op_put_getter_setter bytecode op. Ultimately we should probably be
able to merge this with put direct, to create a common op to initialize
object literal properties.
