Thanks in advance, that would be great.  The weird dance with FP can certainly
be a mightily confusing factor for the RTL DSE pass.

On my side, I have bootstrapped on good old 32-bit PowerPC/Linux and Ada is in
nominal shape here (we're slowing migrating to 64-bit... big-endian for now).
Thanks to Marc, I'll try to reproduce the issue on gcc2-power8, but the system
compiler doesn't come with Ada so this may take some time.
