This patch removes gfc_ss::codimen field and any code depending on it.

OK?
2011-09-14  Mikael Morin  <mikael.morin@sfr.fr>

	* trans.h (gfc_ss_info): Remove codimen field.
	* trans-array.c (gfc_get_array_ss): Don't set codimen field.
	(gfc_trans_create_temp_array): Don't set descriptor's cobounds.
	(gfc_trans_constant_array_constructor): Update loop upper limit.
	(gfc_conv_ss_startstride): Don't set codimen field.
	Don't get descriptor's cobounds.
	(gfc_walk_variable_expr): Update dimension index.
	* trans-intrinsic.c (trans_this_image, trans_image_index,
	conv_intrinsic_cobound): Don't set codimen field
