    rs6000/doc: Rename future cpu with power10
    
    Commmit 5d9d0c94588 renamed future to power10 and ace60939fd2
    updated the documentation for "future" renaming.  This patch
    is to rename the remaining "future architecture" references in
    documentation and polish the words for float128.
    
    gcc/ChangeLog:
    
            * doc/invoke.texi: Change references to "future cpu" to "power10",
            "-mcpu=future" to "-mcpu=power10".  Adjust words for float128.
