Adding a MIPS hardware bug work-around to GAS...

Hi Steven,

> I am trying to work-around a hardware bug 

Note that in general patching software to work around a hardware bug is 
a bad idea.  Hardware designers should always be encouraged to 
thoroughly test their designs before releasing them.  In the real world 
of course patching the software is often a lot cheaper than fixing the 
hardware so this kind of thing does happen.  *sigh*

There is already a precedent for doing this.  See the code for the 
-mfix-vr4120 in gas/config/tc-mips.c for an example.
