[PATCH, rs6000] Add support to __builtin_cpu_supports() for new HWCAP2 bit

[Peter Bergner]

There is a new HWCAP2 bit added to the AUXV here:

  http://patchwork.ozlabs.org/patch/824764/

This patch adds __builtin_cpu_supports() support for it.
This passed bootstrap and regtesting with no regressions?
Ok for trunk?

Ok to back port to the open releases too once testing to complete there?

Peter
