This patch is the second part to allow TFmode to be IBM extended double or IEEE
128-bit floating point depending on switches.

I have built the compiler with this patch and the previous subpatches (1-12).
I have bootstrapped the compiler with all 16 subpatches installed, and there
were no regressions.  Is it ok to install in the trunk?
