This avoids bigger than V2DF vectorization which disturbs the ability
to consistently check for the vectorization result after us now
also vectorizing the V2DF tail of a V4DF vectorization variant.

tested on x86_64-unknown-linux-gnu, pushed.

	* gcc.dg/vect/bb-slp-pr65935.c: Prefer 128bit vectorization
	on x86.
