[Bug optimization/15068] New: ICE in elim_reg_cond

["pb at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This code:

$ cat s_fmax.i
double
__fmax (double x, double y)
{
  return (__builtin_isgreaterequal(x, y) || (sizeof (y) == sizeof (float) ? 
__isnanf (y) : __isnan (y))) ? x : y;
}

crashes an arm-linux compiler when invoked as:

$ ./cc1 -O2 ~/s_fmax.i
 __fmax
