PR tree-optimization/53410
	* fold-const.c (fold_binary_loc): Use build_zero_cst (type)
	instead of build_int_cst (type, 0) where vector types might be
	involved. Instead of build_int_cst (type, 1) convert the original
	integer_onep argument to the desired type.

	* gcc.c-torture/compile/pr53410-1.c: New test.
	* gcc.c-torture/compile/pr53410-2.c: New test.
