Ilya Leoshkevich 9b21049edd target/i386: Make sure that vsyscall's tb->size != 0 
tb_gen_code() assumes that tb->size must never be zero, otherwise it
may produce spurious exceptions. For x86_64 this may happen when
creating a translation block for the vsyscall page.

Fix by pretending that vsyscall translation blocks have at least one
instruction.
