    Change TARGET_FPRND to TARGET_POWER5X
    
    As part of the architecture flags patches, this patch changes the use of
    TARGET_FPRND to TARGET_POWER5X.  The FPRND instruction was added in power5+.
    
    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.cc (report_architecture_mismatch): Use
            TARGET_POWER5X instead of TARGET_FPRND.
            * config/rs6000/rs6000.md (fmod<mode>3): Use TARGET_POWER5X instead of
            TARGET_FPRND.
            (remainder<mode>3): Likewise.
            (fctiwuz_<mode>): Likewise.
            (btrunc<mode>2): Likewise.
            (ceil<mode>2): Likewise.
            (floor<mode>2): Likewise.
            (round<mode>): Likewise.
