    rs6000: Redo darn (PR103624)

    The builtins now all return "long".  The patterns have :GPR as the
    output mode, so they can be 32-bit as well (the instruction makes sense
    in 32 bit just fine).  The builtins expand to the DImode version
    normally, but to the SImode if {32bit} is true.
