	* gcc/tree-scalar-evolution.c (number_of_iterations_in_loop):
	changed to be wrapper of number_of_iterations_in_loop_1
	(number_of_iterations_in_loop_1): New. Same as previous
	number_of_iterations_in_loop, but takes new argument may_be_zero.
	* gcc/tree-scalar-evolution.h (number_of_iterations_in_loop_1): New
	prototype.
	* gcc/tree-ssa-loop-ivopts.c (expr_invariant_in_loop_p): return true
	for DECL expressions.
	* gcc/tree-vect-analyze.c (vect_get_loop_niters): call to
	number_of_iterations_in_loop_1 instead of number_of_iterations_in_loop.
	* gcc/passes.c (init_optimization_passes): call to dce before
	vectorizer.
