Changed the dimensions of __CTOR_LIST__ and __DTOR_LIST__ from 0
to 2. This makes them agree with the declarations in libgcc, and
clears the way once again for linking c++rt0.o into all libraries,
and eliminating CPLUSPLUSLIB from <bsd.lib.mk>. (I have not made
that change yet, because there is still a bootstrapping problem
for "make world".)
Also, removed a check which ensured that the constructor count in
the first word of __CTOR_LIST__ was greater than zero before
traversing the list. I had added that check earlier, but it is no
longer necessary, now that there is guaranteed to be at least 2
words in __CTOR_LIST__.
