MIPS64 XLR support patch

Joseph S. Myers joseph@codesourcery.com
Thu Jan 29 14:27:00 GMT 2009 
A patch was submitted last May
<http://sourceware.org/ml/binutils/2008-05/msg00214.html> to add
support for the MIPS64 XLR processor.  It was not reviewed, despite
being pinged twice
<http://sourceware.org/ml/binutils/2008-06/msg00057.html>
<http://sourceware.org/ml/binutils/2008-06/msg00137.html>, after which
the submitter apparently gave up.

I've updated this patch for current HEAD, lightly cleaned it up and
rewritten the ChangeLog entries.  Daniel has confirmed that RMI has a
copyright assignment for GCC and Binutils on file.  Tested with no
regressions with cross to mips64-linux-gnu.  OK to commit?
