Assign-ops and incdec on overloaded properties are implemented using a read_property followed by write_property. Previously, if __get() returned by-reference, pre-incdec and assign-op additionally also modified the reference, while post-incdec worked correctly. This change synchronizes the three code-paths to not modify the reference. The pre-incdec implementation matches the post-incdec implementation, the assign-op implementation uses a distinct result operand.
