        * trans-array.c (gfc_trans_create_temp_array): If n is less
	than the temporary dimension, assert that loop->from is
	zero (reverts to earlier versions). If there is at least one
	null loop->to[n], it is a callee allocated array so set the
	size to NULL and break.
	(gfc_trans_constant_array_constructor): Set the offset to zero.
	(gfc_trans_array_constructor): Remove loop shifting around the
	temporary creation.
	(gfc_conv_loop_setup): Prefer zero-based descriptors if
	possible.  Calculate the translation from loop variables to
	array indices if an array constructor.
