If we have split a parallel I2 to two insns, we will count its RTL cost
twice.  This currently does not matter since the cost is 0 always (it is
not a single set insn), but let's fix it anyway.

Also do not display the fake I1 in the cost calculation in the dump file.

Tested on powerpc64-linux.  Okay for mainline?

        split I2 twice.  Do not display it twice in the dump, either.

OK.
