Disallow TFmode and TDmode from reg+reg addressing

This ICE is similar to the one Nathan fixed which is caused by the new 
gcc_assert Joseph added here:

  http://gcc.gnu.org/ml/gcc-patches/2007-09/msg01959.html

I agree with Joseph's suggestion from Comment #5 that we need to disallow
TFmode (and TDmode) similar to Nathan's patch.  This patch fixes the ICE
on the test case.  I'm running a full bootstrap with it now on powerpc64-linux.

        * config/rs6000/rs6000.c (rs6000_legitimize_address): Don't generate
        reg+reg addressing for TFmode or TDmode quantities.
