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.
