    rename floatformat_ia64_quad_{big, little} to floatformat_ieee_quad_{big, little}
    
    I submitted a GDB patch [1] to rename floatformats_ia64_quad to
    floatformats_ieee_quad to reflect the reality, and then we can
    clean up the related code.
    
    As GDB Global Maintainer Tom Tromey said [2]:
    
      These files are maintained in gcc and then imported into the
      binutils-gdb repository, so any changes to them will have to
      be proposed there first.
    
    this GCC patch is preparation for the GDB patch, no functionality
    change.
