An rs6000 maintainer should review this to be sure that all vector types
of a given width should be treated identically.

My rationale here was that SPE vectors are all exactly 8-byte wide, while Altivec vectors are all exactly 16-byte wide.

	* config/i386/i386.c (function_arg): Always treat 8-
	and 16-byte wide vectors the same, even if MMX/SSE
	are disabled.
	(contains_128bit_aligned_vector_p): Add comment.

Applied.

Thanks.

Paolo
