* BaseException_vectorcall() now creates a tuple from 'args' array. * Creation an exception using BaseException_vectorcall() is now a single function call, rather than having to call BaseException_new() and then BaseException_init(). Calling BaseException_init() is inefficient since it overrides the 'args' attribute. * _PyErr_SetKeyError() now uses PyObject_CallOneArg() to create the KeyError instance to use BaseException_vectorcall().
