    Change TARGET_MODULO to TARGET_POWER9
    
    As part of the architecture flags patches, this patch changes the use of
    TARGET_MODULO to TARGET_POWER9.  The modulo instructions were added in power9 (ISA
    3.0).  Note, I did not change the uses of TARGET_MODULO where it was explicitly
    generating different code if the machine had a modulo instruction.
    
    I have built both big endian and little endian bootstrap compilers and there
    were no regressions.
    
    In addition, I constructed a test case that used every archiecture define (like
    _ARCH_PWR4, etc.) and I also looked at the .machine directive generated.  I ran
    this test for all supported combinations of -mcpu, big/little endian, and 32/64
    bit support.  Every single instance generated exactly the same code with the
    patches installed compared to the compiler before installing the patches.
    
    Can I install this patch on the GCC 15 trunk?

            * config/rs6000/rs6000-builtin.cc (rs6000_builtin_is_supported): Use
            TARGET_POWER9 instead of TARGET_MODULO.
            * config/rs6000/rs6000.h (TARGET_CTZ): Likewise.
            (TARGET_EXTSWSLI): Likewise.
            (TARGET_MADDLD): Likewise.
            * config/rs6000/rs6000.md (enabled attribute): Likewise.
