[PATCH] gcc: rename floatformat_ia64_quad_{big, little} to floatformat_ieee_quad_{big, little}

[Tiezhu Yang <yangtiezhu@loongson.cn>]

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.

Hi GCC Maintainers,

I have no write access of gcc.git, if you are OK with this change,
could you please help me to merge this patch to the gcc master?
Thank you.
