Programming error in emit-rtl.c

[Jesse M Draper]

The call to xcalloc at emit-rtl.c:3988 in 3.0.2 has an extra factor of
sizeof (rtx).  Instead of
xcalloc(f->emit->regno_pointer_align_length * sizeof (rtx),
	sizeof (rtx));
it should be
xcalloc(f->emit->regno_pointer_align_length, sizeof (rtx))

As far as I can see, this won't cause a bug since it allocates more
space than is necessary.  I saw no problem with subsequent calls to
xrealloc, but I wasn't sure that that would be the only possible
source of interactions.
