altivec: altivec.h

[Aldy Hernandez]

*sigh*  more of the same

vec_ctu() needed a cast.  fixed.

and the parenthesizing patch from alan matsuoka was causing syntax errors 
with jason's vector literal patch with parentheses.  so i fixed vec_step()
to remove the extraneous parentheses.

committed as obvious to branch and trunk.

have i mentioned we need proper function overloading in C?

	* config/rs6000/altivec.h (vec_step): Remove extraneous
	parentheses.
	(vec_ctu): Cast return.
