So the two loads don't need to be directly adjacent in the generated code, as the test originally required here? 
Looks like they are no longer adjacent with this patch because an offset is no longer folded into the second load. There are other tests in this file checking that offsets are folded(for example `load_v8float`), so these `load_sampler` tests probably don't need to check that.
