This is a partial implementation of PEP 448 to allow multiple ** unpackings when calling a function or method. The compiler is modified to encode the argument as a None: obj key-value pair (similar to how regular keyword arguments are encoded as str: obj pairs). The extra object that was pushed on the stack to hold a single ** unpacking object is no longer used and is removed. The runtime is modified to decode this new format.
