Log message:
	PR fortran/15080
	* trans-stmt.c (generate_loop_for_temp_to_lhs): Remove SIZE and COUNT2
	arguments.  If LSS is gfc_ss_terminator, increment COUNT1 by 1, instead
	of incrementing COUNT2 and using COUNT1+COUNT2 increment COUNT1 and use
	just that as index.
	(generate_loop_for_rhs_to_temp): Likewise.
	(compute_overall_iter_number): Add INNER_SIZE_BODY argument.
	It non-NULL, add it to body.
	(allocate_temp_for_forall_nest_1): New function, split from
	allocate_temp_for_forall_nest.
	(allocate_temp_for_forall_nest): Add INNER_SIZE_BODY argument,
	propagate it down to compute_overall_iter_number.  Use
	allocate_temp_for_forall_nest_1.
	(gfc_trans_assign_need_temp): Remove COUNT2.  Call
	compute_inner_temp_size into a new stmtblock_t.  Adjust calls to
	allocate_temp_for_forall_nest, generate_loop_for_rhs_to_temp
	and generate_loop_for_temp_to_lhs.
	(gfc_trans_pointer_assign_need_temp): Adjust calls to
	allocate_temp_for_forall_nest.
	(gfc_evaluate_where_mask): Call compute_inner_temp_size into a new
	stmtblock_t.  Call compute_overall_iter_number just once, then
	allocate_temp_for_forall_nest_1 twice with the same size.
	Initialize mask indexes if nested_forall_info != NULL.
	(gfc_trans_where_2): Initialize mask indexes before calling
	gfc_trans_nested_forall_loop.
	
	* gfortran.fortran-torture/execute/forall_3.f90: Remove comment
	about the test failing.
	* gfortran.fortran-torture/execute/where_7.f90: New test.
	* gfortran.fortran-torture/execute/where_8.f90: New test.
