[rs6000] x86 vector intrinsics compatibility: clean-ups for 32bit support

Implement various corrections in the compatibility implementations of the
x86 vector intrinsics found after enabling 32bit mode for the associated
test cases.  (Actual enablement coming in a subsequent patch.)

2018-10-26  Paul A. Clarke  <pc@us.ibm.com>

gcc/ChangeLog:

	* config/rs6000/mmintrin.h: Enable 32bit compilation.
	* config/rs6000/xmmintrin.h: Likewise.
