As discussed on python-dev, removed from DUP_TOPX support for the

parameter being either four or five.  Currently, compile.c does not
generate calls with a parameter higher than three.

May have to be reverted if the second alpha or beta shakes out some
other tool generating this op code with a parameter of four or five.
