The order of the elements in the stack was incorrect.  It seems that, in
general (for all CALL_FUNCTION opcodes), the correct order is (from bottom to
top):
   function
   positional arguments
   [star arg tuple]
   keyword arguments
   [keyword dictionary]
   CALL_FUNCTION[_..]
Fixes [bug 33216](https://bugs.python.org/issue33216).

Use 'var-keyword' and 'var-positional' to better specify the items in the
stack.
Describe each opcode by stating the difference with CALL_FUNCTION.
