This has a simple fix that I have tested on power8 and Seurer are
tested on power9.

While there may be a more elegent coding for the require casts, this is
the simplest change, considering the current stage.

	* config/rs6000/mmintrin.h (_mm_cmpeq_pi32 [_ARCH_PWR9]):
	Cast vec_cmpeq result to correct type.
	* config/rs6000/mmintrin.h (_mm_cmpgt_pi32 [_ARCH_PWR9]):
	Cast vec_cmpgt result to correct type.
