gcc-3.4.x patch for IA-64 SPEC2000 miscompilation

I have backported a patch from mainline to the gcc-3.4.x branch in order
to fix a SPEC2000 miscompilation problem the SPEC2000 FP 173.applu
benchmark was miscompiled at -O2, because FP registers were being
saved/restored around calls as DImode values.  This patch defines
HARD_REGNO_CALLER_SAVE_MODE to force them to be saved/restored as XFmode
values.

The Changelog entry is a little nonstandard, but that is the way it is
on mainline, and it seemed wrong to "fix" it when backporting it to the
gcc-3.4.x branch.  Normally testsuite ChangeLog entries are put in the
testsuite/ChangeLog file.  I see others have made the same mistake.
