gdb: rename floatformats_ia64_quad to floatformats_ieee_quad

Browse Source 
It is better to rename floatformats_ia64_quad to floatformats_ieee_quad
to reflect the reality, and then we can clean up the related code.

As Tom Tromey said [1]:

  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.

the related changes have been merged into gcc master now [2], it is time
to do it for gdb.
