After the patch it looks like this:

* NDS32 Built-in Functions::
* picoChip Built-in Functions::
* Basic PowerPC Built-in Functions::
* PowerPC AltiVec/VSX Built-in Functions::
* PowerPC Hardware Transactional Memory Built-in Functions::
* PowerPC Atomic Memory Operation Functions::
* RX Built-in Functions::
* S/390 System z Built-in Functions::

I think it is nicer to just have a single "PowerPC Built-in Functions"
node, with then everything else hanging from a menu in there (as you have
for "Basic PowerPC Built-in Functions" now; so just rename that and put
the V*X, TM, atomic nodes in that menu too; probably need to make those
subsubsections or such).

But please commit this now, it's a nice improvement already.  Thanks!
