	PR fortran/30404
	* trans-stmt.c (forall_info): Remove pmask field.
	(gfc_trans_forall_loop): Remove NVAR argument, instead assume that
	NVAR covers all the interation variables in the current forall_info.
	Add an extra OUTER parameter, which specified the loop header in
	which to place mask index initializations.
	(gfc_trans_nested_forall_loop): Remove NEST_FLAG argument.
	Change the semantics of MASK_FLAG to only control the mask in the
	innermost loop.
	(compute_overall_iter_number): Optimize the trivial case of a
	top-level loop having a constant number of iterations.  Update
	call to gfc_trans_nested_forall_loop.  Calculate the number of
	times the inner loop will be executed, not to size of the 
	iteration space.
	(allocate_temp_for_forall_nest_1): Reuse SIZE as BYTESIZE when
	sizeof(type) == 1.  Tidy up.
	(gfc_trans_assign_need_temp): Remove NEST_FLAG argument from calls
	to gfc_trans_nested_forall_loop.
	(gfc_trans_pointer_assign_need_temp): Likewise.
	(gfc_trans_forall_1): Remove unused BYTESIZE, TMPVAR, SIZEVAR and
	LENVAR local variables.  Split mask allocation into a separate
	hunk/pass from mask population.  Use allocate_temp_for_forall_nest
	to allocate the FORALL mask with the correct size.  Update calls
	to gfc_trans_nested_forall_loop.
	(gfc_evaluate_where_mask): Update call to
	gfc_trans_nested_forall_loop.
	(gfc_trans_where_2): Likewise.

	* gfortran.dg/forall_6.f90: New test case.
	* gfortran.dg/dependency_8.f90: Update test to find "temp" array.
	* gfortran.dg/dependency_13.f90: Likewise.
