	* tree-vectorizer.h (vectorizable_function): Export.
	* tree-vect-transform.c (vectorizable_function): Likewise.
        * tree-vect-patterns.c (vect_recog_pow_pattern): Set
        type_in to scalar type in recognition of squaring.
	Make sure the target can vectorize sqrt in recognition
	of sqrt, set type_in to vector type in this case.

	* gcc.dg/vect/vect-pow-1.c: Rename ...
	* gcc.dg/vect/fast-math-vect-pow-1.c: ... to this.  Use
	floats instead of doubles, check successful vectorization.
