    rs6000: Fix ICE in rs6000_init_builtins when compiling with -mcpu=440
[PR99279]

    The initialization of compat builtins assumes the builtin we are creating
    a compatible builtin for exists and ICEs if it doesn't.  However, there are
    valid reasons why some builtins are disabled for a particular compile.
    In this case, the MMA builtins are disabled for -mcpu=440 (and other cpus),
    so instead of ICEing, we should just skip adding the MMA compat builtin.
