py/runtime: Allow multiple *args in a function call.
This is a partial implementation of PEP 448 to allow unpacking multiple
star args in a function or method call.
This is implemented by changing the emitted bytecodes so that both
positional args and star args are stored as positional args. A bitmap is
added to indicate if an argument at a given position is a positional
argument or a star arg.
In the generated code, this new bitmap takes the place of the old star arg.
It is stored as a small int, so this means only the first N arguments can
be star args where N is the number of bits in a small int.
The runtime is modified to interpret this new bytecode format while still
trying to perform as few memory reallocations as possible.
