re PR middle-end/43901 (FAIL: gcc.c-torture/compile/pr42196-2.c)

	PR tree-optimization/43901
	* tree-vect-stmts.c (vectorizable_call): Assert that vector
	type is not NULL if it's transformation phase, and return
	FALSE if it's analysis.
	(vectorizable_conversion, vectorizable_operation, 
	vectorizable_type_demotion, vectorizable_type_promotion):
	Likewise.
