When gigi builds an indexed component reference with a variable index, it marks
the array object as addressable. This was probably necessary back in the RTL
days but this is very likely obsolete by now.
Tested on i586-suse-linux, applied on the mainline.

* gcc-interface/utils2.c (build_binary_op) <ARRAY_REF>: Do not mark the
left operand as addressable.
