Synopsis: '-mcpu=xscale -fno-strict-aliasing -O2' generates wrong code

State-Changed-Why:
    Confirmed.  The same bug does not occur with the latest compiler, but I think that's because an earlier pass of the compiler has optimized the problem away before it trips the bug.  
    
    Initial investigation suggests this is a problem with reload_combine().
