[Patch, fortran] Remove gfc_array_ref::offset field


The offset field is never set; this patch removes it.

Regression tested on x86_64-unknown-linux-gnu. OK for trunk?

2012-07-27  Mikael Morin  <mikael@gcc.gnu.org>

	* array.c (gfc_copy_array_ref): Don't copy the offset field.
	* expr.c (find_array_section): Ignore the offset field.
	* trans-expr.c (gfc_find_interface_mapping_to_ref): Don't apply
	interface mapping to the offset field.
	* gfortran.h (struct gfc_array_ref): Remove the offset field.
