rs6000: Remove no longer correct assert

After the simplify-rtx patch, we can now be asked about conditions we
wouldn't be asked about before.  This is perfectly fine, except we
have a little over-eager assert.  Remove that one.


	* config/rs6000/rs6000.c (validate_condition_mode): Don't assert for
	valid conditions.
