target/arm: Make sure that commpage's tb->size != 0
tb_gen_code() assumes that tb->size must never be zero, otherwise it
may produce spurious exceptions. For ARM this may happen when creating
a translation block for the commpage.
Fix by pretending that commpage translation blocks have at least one
instruction.
