                         __sparc_utrap_setup.c 
  Added files:
    lib/libc/sparc64/sys __sparc_utrap_emul.c 
  Log:
  Emulate ldq and stq (load/store long double) instructions.  GCC has started
  using these to load long doubles, but they aren't implemented in hardware
  on (at least) UltraSPARC I and II machines.
  Emulate popc in the user trap handler as well.
  Re-arrange slightly to make support functions more accessible.
