 Log:
   MFC: r206490, r206492
   
   While SPARC V9 allows tininess to be detected either before or after
   rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
   UltraSPARC processors defines that in all cases tininess is detected
   before rounding therefore rounding up to the smallest normalized number
   should set the underflow flag. This change is needed for using SoftFloat
   on sparc64 for reference purposes.
