[Patch, fortran] [14/66] inline sum and product: Interfaces changes: gfc_trans_array_bound_check, gfc_conv_array_index_offset

The next patch is going to need array expression (available through gf_ss) 
instead of just the array descriptor in gfc_trans_array_bound_check. This makes
the gfc_ss struct available as argument.
This requires an update of gfc_conv_array_index_offset too.
Both functions are static, they lose their gfc_ prefix along the way.
OK?

	* trans-array.c (gfc_trans_array_bound_check,
	trans_array_bound_check): Rename the former to the latter.
	Replace descriptor argument with ss argument.  Get descriptor from ss.
	(gfc_conv_array_index_offset, conv_array_index_offset): Rename the
	former to the latter.  Update call to trans_array_bound_check.
	Replace info argument with ss argument.  Get info from ss.
	(gfc_conv_scalarized_array_ref): Update call to conv_array_index_offset.
	(add_array_offset): Ditto
