arb_fragment_shader_interlock: Simple compiler tests

Currently none of the negative tests produce the expected result on
Mesa.  There are other cases called out by the spec as things you cannot
do, but it's not clear what the expected result is in those cases
(compile- or link-time error, undefined rendering, GPU hang, house fire,
etc.).
