This is in preparation for a patch that disables folding offsets into FLAT instructions if the corresponding address computation is not inbounds, to avoid miscompilations where this would lead to wrong aperture check results. With the added inbounds flags for GEPs and G_PTR_ADDs affecting FLAT instructions, the outputs for these tests won't change. For SWDEV-516125.
